Likely your JDK/JRE is too new for the swig version in the nexus branch. Try using and older JDK or newer swig.

Hi HiassofT - I am using swig 4.4.1 and jre-openjdk 21.u35.  I didn't find any documentation for supported versions.  What you you recommend trying?

[HiassofT]

Hmm, weird, just checked on https://javaalmanac.io/bytecode/versions/ and class file version 65 would match jre/jdk 21.

And as class files should be backward compatible (i.e. run on newer JREs) that would mean your jre / java is too old (not too new).

Can you check if you have older JREs/JDKs installed as well and double-check the output of "java -version" and "javac -version"? The latter should be identical (i.e. runtime matches compiler)

so long,

Hias

Interesting... here is the output.  I do not have any older packages installed.

Code:

% ./usr/lib/jvm/default-runtime/bin/java -version
openjdk version "21" 2023-09-19
OpenJDK Runtime Environment (build 21+35)
OpenJDK 64-Bit Server VM (build 21+35, mixed mode, sharing)

I do not have a file named "javac" for the 2nd test.
