[COLLECTIONS 714] Add tests

[rohanpadhye]

Adding two tests that demonstrate the bug reported in COLLECTIONS-714. The tests currently fail, since I don't have a fix for the bug.

[garydgregory]

Since the tests fail, please decorate the methods with @ignore("COLLECTIONS-714")

[rohanpadhye]

The @Ignore annotation only appears to work with JUnit4-style tests (org.junit.Test). The PatriciaTrieTest suite appears to using a JUnit3 style (junit.framework.Test), which doesn't support @Ignore. Am I mistaken here?

I have given project maintainers edit access to this pull request, so feel free to push any changes you desire directly to the bug-collections-714 branch.

[garydgregory]

@rohanpadhye You are not mistaken indeed. Commons Collections needs a port to JUnit 4 for @Ignore to to work properly. We cannot merge this patch as is since it will make the build fail.

You can add a prefix of X for those test cases as the JUnit will be looking for the methods starting with test.

Don't do that, that's why one uses @Ignore.
