Class file version error in DSE with SpecificationReader

[vrichthammer]

When trying to run a standard DSE (EA, SumEvaluator, sequential completion, standard OptimizationModule), we encounter the following error when using the InputModule with input file opendse-tutorial/spec.xml (and other such xml-specs) (tested with Java 11 and 14).

com.google.common.util.concurrent.UncheckedExecutionException: java.lang.IllegalArgumentException: Unsupported class file major version 58' ' [...] at org.opt4j.core.config.Task.call(Task.java:41) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1130) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:630) at java.base/java.lang.Thread.run(Thread.java:832)' ' Caused by: java.lang.IllegalArgumentException: Unsupported class file major version 58 at com.google.inject.internal.asm.$ClassReader.<init>(ClassReader.java:176) [...] ... 21 more

• A DSE with the same opt4j-config works when using InputTgff with the included tgff-spec instead
• Reading the above-mentioned spec-files in a test class using a newly created instance of the SpecificationReader works as well

I could narrow down the bug a bit: The problem seems to occur when multiple different DSEs are started with different specs from the GUI. I corrected the import of Opt4J to release 3.3.0. Further investigation is required to debug what exactly causes the problem in the SpecificationReader when a second optimization is launched and why a Java version exception ('file major version 58' has to do with Java 14 being used) occurs.

Could you try it with Odse as present in the bugFixSpecRead branch?

opendse-tutorial/specs/Specification*.xml all work for me now with Java 11.

opendse-tutorial/spec.xml no longer causes the major version error, but results in a different set of errors, so there might be a problem with this specific specification:
