prevent raw type warnings in tests

[hduelme]

What it does

I removed the raw type warnings from the tests. Currently hundreds of times the following is written to console:

----------
1. WARNING in /tmp/comptest/run.1722929041244/verifier/org/eclipse/jdt/core/tests/util/VerifyTests.java (at line 57)
     Class testClass = urlClassLoader.loadClass(className);
     ^^^^^
Class is a raw type. References to generic type Class<T> should be parameterized
----------
2. WARNING in /tmp/comptest/run.1722929041244/verifier/org/eclipse/jdt/core/tests/util/VerifyTests.java (at line 60)
     Method main = testClass.getMethod("main", new Class[] {String[].class});
                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Type safety: The method getMethod(String, Class...) belongs to the raw type Class. References to generic type Class<T> should be parameterized
----------
2 problems (2 warnings)

I added -warn:-raw -warn:-unsafe to the compiler options for compileVerifyTests to prevent this.

One thing I noticed. The code causing this is explicate marked to be compatible with Java 5 language level. If I see it correctly the minimum Java language level is currently 8 for tests. The better solution would be to make the code Java 8 compatible and remove the Java 5 filtering.

How to test

Check the console, no such warnings anymore.
