I just thought i share some wisdom i obtained recently. This still not means there is no need for a 64-Bit Java wrapper but it can help for now as workaround to resolve Issues.
You can get 32\64 Bit OpenJDK through https://adoptopenjdk.net/.
I installed x86 version as Hotspot and x64 as OpenJ version (same not possible through their installshieldshield kit). I can run Eclipse Version: 2019-09 R (4.13.0) without any issues. as Systemenvirement i used C:\Program Files (x86)\AdoptOpenJDK\jdk-13.0.2.8-hotspot.
Now it seems Eclipse takes x64 to run java and allow me to build .jar files. Delphi on the other side takes x86 version and i can import java written plugins. So far it looks doable as workaround but there is no 100% safety it will work in all aspects. Still testing… still researching.
