Java compliance level

[Daniels118]

This question is mainly directed to Puybaret.

The Plug-in developer's guide states:

If you want your plug-in to be able to run with Sweet Home 3D installers available on this web site, take care to keep it compliant with Java 5

I think this requirement was valid for a very old release, since the latest installer comes with Java 11, however I could be missing something not so obvious.

So, the question is:
which Java compliance level could we safely use for new plugins?

[Puybaret]

Current installers are bundled (or runs) with the following Java versions:
- Windows 32 bit and Linux versions run with Oracle Java 8u202
- Windows 64 bit version runs with OpenJDK 11
- macOS 10.4 Intel version runs with Apple Java 5
- macOS 10.5 to 10.8 Intel version runs with Apple Java 6
- other macOS Intel versions run with Oracle Java 8u202 or OpenJDK 15
- macOS ARM version runs with OpenJDK 15
and Java Web Start users are probably almost all using Java 8.

Nowadays, there are probably almost no macOS 10.4 users and very few macOS 10.5 to 10.8 users.
So I guess you could require Java 8 if needed (i.e. [font=courier new]javaMinimumVersion=1.8[/font]).
