Reason: The test starts the JVM with 3m code cache and 64 compiler threads. As a result, it is very likely that not all compiler threads can be started due to insufficient space in the code cache. It is also possible that the initialization of all compiler threads of a particular compiler (C1/C2) fails. Since the test starts the JVM with -Xcomp (blocking compilation) the JVM waits forever for the compilation to complete. However, the compilation cannot complete, since there is no compiler thread to process the task.
