Java3D cannot parse Java versions that are not numerical

I had Java3d running fine in Java 14.
But I had to upgrade the Java version to version 15 (early release) because of a bug in Java 14 which is only fixed in Java 15.

But looks like Java3D cannot parse early release versions of Java!
I get this exception:

Hello

Thank you for the feedback. I'll provide a patch to Phil when I have some time.

By the way, the bug fixes are backported into long term support versions... in theory.

Please can you tell me which bug forced you to upgrade?

Certainly.
Here's the jdk bug:
https://bugs.openjdk.java.net/browse/JDK-8237490

It doesn't seem to be backported.
I had the latest Java 14 version before I was forced to make this upgrade.

A similar fix should be used in Java3D:
https://sourceforge.net/p/tuer/code/HEAD/tree/pre_beta/src/main/java/engine/misc/DeallocationHelper.java#l330

Thanks for this, somehow my spam folder caught this and didn't tell me.

I'll get this into the 1.7 line of Java3D, then give Harvey a pull request for Java3D 1.6

Hi @philjord
Did you manage to get this fix in 1.7?
If so, where can I download its jar file?

Looking at the link below looks like the latest 1.7 built was in Feb 2020:
