Fastdebug VM crashes because of assertion failure on windows-amd64 when different valid combinations of -agentlib:jdwp are used. (for example "-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8000", "-agentlib:jdwp=transport=dt_shmem,server=y,suspend=n"). Failure reproduces even with HelloWorld application (this failure also reproduces with fastdebug mustang b105).
