Constant Pool tag 18 is CONSTANT_InvokeDynamic. This wasn't being emitted by the Java compiler for the example code when the interpreter was written.

Which Java version are you compiling with? I think using an older version will probably work. Or adding InvokeDynamic support to python-jvm-interpreter.

temurin 21, can you at least add a warning or assertion warning about the jdk version, thank you, Ill try with older jdk
