EVALUATION

Both issues are not bugs, but compatibility issues for developers who relied on JDK implementation details rather then API and specification.
We have fixes for both issues ready and safe. If we apply them to 7u6 we must do additional changes for 7u7 (since fix for 7182135 touches code that was changed in 7u7).
