------------------------------------

Hey [~zero45], re: the test failure for hadoop.hdfs.TestStateAlignmentContext, 
it passed when I ran it locally, and also this patch doesn't touch anything 
that should affect that test. I am wondering if the test is flaky. Can you look 
into it?

Regarding the javac output, I didn't touch QJMTestUtil at all, not sure why it 
is complaining there but it does not look like an issue in the patch.
