Bug: https://bugs.openjdk.java.net/browse/JDK-8205966 webrev: http://cr.openjdk.java.net/~dholmes/8205966/webrev/
One of the @run variants was taking around 15x longer to execute. That variant uses the InMemoryJavaCompiler which involves a lot of classes and code execution. The test was enabling method entry event generation for all of main, resulting in the massive slowdown.
The fix is to add a new breakpoint() function that gets called after the in-memory compilation setup is done, and we initially run the test to that point before enabling the events.
The problem @run now only takes 2x the other tests and so should avoid the timeouts.
