JPRT and TL nightly testing periodically see failures with the following tests on Windows:

java/nio/channels/FileChannel/ReleaseOnCloseDeadlock.java
java/nio/channels/AsynchronousSocketChannel/Basic.java

The underlying issue is an awkward corner case 7052549 that is specific to Windows. As that issue is going to take a bit of time to resolve (and is not high priority because it's mostly harmless) we need to put these tests on the jdk problem list.
