This PR enables CI for java tests by adding --java-bindings to ci.yml. It also replaces the unreliable finalize method and instead uses AutoCloseable and explicit close method to clean up dynamic memory allocated by java native interface. The PR fixes compile errors for SolverTest.java and runtime errors for Solver.defineFun.
