Previously, we were using io.github.cvc5.api to mirror the C++
namespace that the API was in. The namespace of the C++ API changed to
simply cvc5 and so this commit updates the Java package accordingly.
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.
This PRs updates java examples using the new Java API, by converting C++ examples to Java.
Examples CVC4Streams.java and PipedInput.java are removed since they are not longer supported by the API.
All examples are not included in the build which would be added in a future PR.
This PR updates the update-copyright.pl script to also update/add copyright headers to CMake specific files. It further fixes a small typo in the header.
