RandomHelper needs updates

./CTFRun.sh ../src/tests/xml/MasterTestSuite/sourcegenerator/Collections/CollectionOfPrimitives/

This test (which I didn't delivery before) used to work. It fails with complaints such as:

/home/ekuns/workspace/castor-2/bin/../build/tests/output/CollectionOfPrimitives/MainType.java:738: incompatible types
found : java.util.Collection
required: java.util.List
_booleanArrayList = RandomHelper.getRandom(_booleanArrayList, boolean.class);
^

I expect this will be easy to fix and I am to fix before Castor 1.1.
