Oxygene with java 11

Is it possible to configure Oxygene/Elements/VisualStudio for use with OpenJDK 11 or above?

Hi Mark,

Elements should work with any version of Java from 7 (oldest one we ever tested) up to the latest. It will automatically pick top the version installed, but you can also manually provide a path to override it, if yu have more than one version installed, or have it installed in a n on-default way/location.

see Setting up the Java Development Kit for Visual Studio for more details.

Did you run into any problems, or just asking preemptively?

yours,
marc

I cannot create a java console app under OpenJDK 11.

Synopsis:
Windows 10
MS Visual Studio 2019 with Elements.10.0.0.2557

Newly installed AdoptOpenJDK 11 (both JDK and JRE) so that

> java -version
openjdk version "11.0.9.1" 2020-11-04
OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.9.1+1)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.9.1+1, mixed mode)

Options in MS Visual Studio:

Continue with: File/New/Project…/ Console Application (Java)

Program.pas with ‘The magic happens here.’ appears.

References include cooper and rt. The latter is not resolved (yellow triangle).

Build yields:

|Error||() Reference ‘rt’ could not be resolved for target ‘Cooper’ (Cooper Plain jvm).|consoleapplication3|C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\RemObjects Software\Elements\RemObjects.Elements.Cooper.targets|53||

Which is expected, because there is no rt.jar in OpenJDK 11.

So, what to do in this case?

Mark,

first of all, can you update to a more recent Elements build, jic? 2557 is a few months behind.

Can yu turn on the most details log level under Tools|Options, P{projects & Solutions, do a Clean/Rebuild, and send me the complete build log? it might give more details as to why it cannot resolve the rt reference.

I assume the Java Runtime and Java SDK paths as set in the dialog above are valid and exist?

thanx,
marc

Checked with Elements 10.0.0.2587. It behaves exactly the same.

As much as I can see, the problem is that your project template (or some other mechanism while creating a project) requires a reference to rt.jar. But newer java distributions, including OpenJDK 11 and AdoptOpenJDK 11, do not include rt.jar any more. This is well known, see for instance

So, the question is how to configure an Oxygene project to cope with this. What else is required to get it working? How do you test your system with Java JDK 11+? Sorry, I could not find any related documentation.

For what it is worth, this is the Clean/Rebuild log:

As far as I recall this should be handled, but I’'ll have another look.

I’ve just downloaded the very latest OpenJDK I(15), and a new Java project builds fine for me after setting the path to it. key parts from the log:

I believe its been like this since Java 9 — using .jmods instead of the ,jar files; and since its worked back when I updated this and still works with 15, I have a hard time believing 11 is any different.

what could I be missing? Do you a have a jmods subfolder for in your JDK path?

Can you build your project from the command line Wirth ebuild --rebuild --debug and send me the full log? thanx!

Yes, jmods dir is there. I also tried OpenJDK 15 (which also has jmods), with the same results. Obviously, something is wrong with my settings or software setup.

So let’s see first how to properly setup java directories. My current setup is as follows:

The instructions there (highlighted) are not really helpful because they refer to a non-existing rt.jar file. So, is this setting correct? Do I need to setup anything else?

This setting yields the log:

Yeah, those instructions still reflect Java 8; I’ll log an issue to get hat updated. if that folder contains ./jmods, then it should be correct.

Note that when I downloaded the OpenJDK here, I needed to specify a subfolder of where it extracted too, /Users/mh/Downloads/jdk-15.0.1.jdk/Contents/Home, not just /Users/mh/Downloads/jdk-15.0.1.jdk/. But that may be different between Mac and Windows; I will test this myself own Windows in a short bit.

                 JDK found in 'D:\Tmp\jdk-15.0.1'.
                  Libraries found in 'D:\Tmp\jdk-15.0.1\lib'.
                  Java executable found at 'D:\Tmp\jdk-15.0.1\bin\java.exe'.

curious, for me this gives

                  JDK found in '/Users/mh/Downloads/jdk-15.0.1.jdk/Contents/Home'.
                  Libraries found in '/Users/mh/Downloads/jdk-15.0.1.jdk/Contents/Home/jmods'.
                  Java executable found at '/Users/mh/Downloads/jdk-15.0.1.jdk/Contents/Home/bin/java'.

note that it detects ./jmods, while for you it detects ./lib — that is the problem; now to find out why…


So I downloaded the Windows versions of the JDK, just to see if it has a different structure that messes tings up, but with that, it still works, here for me: (it doesn’t ding the java executable, ofc, but that doesnt matter).

                  JDK found in '/Users/mh/Downloads/jdk-15.0.1-win'.
                  Libraries found in '/Users/mh/Downloads/jdk-15.0.1-win/jmods'.
                  Java executable found at ''.

Same on Windows; looks fine

                  JDK found in '\\Mac\Home\Downloads\jdk-15.0.1-win'.
                  Libraries found in '\\Mac\Home\Downloads\jdk-15.0.1-win\jmods'.
                  Java executable found at '\\Mac\Home\Downloads\jdk-15.0.1-win\bin\java.exe'.

What I’ll do next is dry-review the code that detects tis to see what could go wring and then (barring any insight) create a small test app with some extra logging that hopefully you can run locally to help see where its going wrong…

Oh, I see whats going on. you have JRE path set to a folder that exists, but it NOT the JRE path, but does contain lib. So the logic ends up in Java 7 mode, using jre/lib as library folder. Java 9+ dent have a JRE folder any more; the fix is to clear that setting, and only set the JDK.

I’ll see if I can somehow detect this and recover, but essentially, this is configured wrong :wink:

let me know if cleaning that helps; if not we need to investigate further…

Clearing the Java runtime path did help; I did get a running Java console application, finally. But I don’t think it has been configured correctly.

After clearing the JRE path, the Option dialog looks as follows:

See the implied path to jre 1.8.0_271?

EBuild clearly uses this implicit setting, saying:

Reference 'rt' was resolved to 'C:\Program Files (x86)\Java\jre1.8.0_271\lib\rt.jar' for target 'Cooper'.

I don’t think this is correct.

Also notice that I have setJAVA_HOME=D:\Tmp\jdk-15.0.1 and %JAVA_HOME%/bin is the first entry in the PATH. So that:

[D:\RemObjects\consoleapplication2] java -version
openjdk version "15.0.1" 2020-10-20
OpenJDK Runtime Environment (build 15.0.1+9-18)

Hmm, yeah. It still detects the default Java 8 JRE folder, for some reason. Do you need Java 8 or can you uninstall it (as the Java updater recommends)? Uninstalling it should fix this.

Regardless, I’ll investigate what’s going on here and how/if I can prevent/detect a mismatch here.

Hmm, I can’t quite understand how it would find that JRE folder; the only places I look for for the JRE are in the settings, and underneath the JDK.

Can you do me a favor and run this project and give me the output?

I get

The magic happens here.
fJDKFolder /Users/mh/Downloads/jdk-15.0.1-win
GetPath(sJRE) /Users/mh/Downloads/jdk-15.0.1-win
looking for JRE from undernweath JDK: 
final JREFolder 
Libraries found in '/Users/mh/Downloads/jdk-15.0.1-win/jmods'.

note how cant find a JRE anywhere (good).

Archive.zip (1.4 MB)

Settings:
JRE path: C:\Program Files (x86)\Java\jre1.8.0_271 (cleared & implied)
JDK path: D:\Tmp\jdk-15.0.1

[D:\Tmp\0] EBuild.Playground.exe
The magic happens here.
fJDKFolder D:\Tmp\jdk-15.0.1
GetPath(sJRE) C:\Program Files (x86)\Java\jre1.8.0_271
JRE from setting
final JREFolder: C:\Program Files (x86)\Java\jre1.8.0_271
Libraries found in 'C:\Program Files (x86)\Java\jre1.8.0_271\lib'.

It is curious that the same result is obtained even after “C:\Program Files (x86)\Java\jre1.8.0_271” is renamed to something else (as a simulation of java 8 removal). There must be some hidden setting or link somewhere.

At all times, JAVA_HOME points to D:\Tmp\jdk-15.0.1

This means you still have the JRE path hardcoded (despite what VS might how).

If you open Water and to to Tools|Options|Paths, what does it show? also, open %APPDATA%\RemObhects Software\Elements\CooperPaths.xml in a text editor — dies it java the JRE set? is so, can you remove it?

Yes, JRE was in CooperPaths.xml, and deleting it did help. Creating a new Java app works nicely now, so the problem seems solved.

Marc, thank you very much, I appreciate your help. I am glad I learned something new.

Excellent happy to hear!

I had similar problem, fortunetly your advices fixed them.
But now i encountered another one. Oxygene cant see javax.sing or java.awt neither java.beans.

Can I get an example project that shows this? I’m not familiar with those APIs, but I assume they come with the JDK and the respective jmod files re present in thej mods folder?

The same happens to other uses like java.awt for example.
