> From the bug:
> "The problem is most likely that SA will pause the target process while it is running. In this case, the target process is the same as the process that launched SA. That process is also handling the output from SA over a pipe, but when that pipe fills up the process cannot empty it and the SA process is blocked because it cannot write any more output. Deadlock."
> The solutions is to start a separate target process. Dmitry Samersoff has already created a test application for such cases so I've decided to move it on the top level library instead of duplicating it. The test application will reside under test/lib/share/classes/jdk/test/lib/apps and the test under test/lib-test/jdk/test/lib/apps.
