Description
I'm unable to run Model checking when I include the CommunityModules.jar file.
TLC threw an unexpected exception.
This was probably caused by an error in the spec or model.
See the User Output or TLC Console for clues to what happened.
The exception was a java.lang.NoClassDefFoundError
: tlc2/value/impl/KSubsetValue
java --version
openjdk 11.0.13 2021-10-19
OpenJDK Runtime Environment Temurin-11.0.13+8 (build 11.0.13+8)
OpenJDK 64-Bit Server VM Temurin-11.0.13+8 (build 11.0.13+8, mixed mode)
I'm also unclear on whether I should have the CommunityModules.jar, the CommunityModules-deps.jar, or both. Attempting to include any versioned module displays an error:
{0} is not a valid library path location

Research direction
Start by reproducing the failure in Toolbox 1.7.1 with CommunityModules.jar and CommunityModules-deps.jar, using the reported OpenJDK 11 environment. Check how versioned modules are included and use the TLC Console output to trace the missing tlc2/value/impl/KSubsetValue class. Done means model checking works and the correct jar inclusion is documented.
