When running jtreg test java/lang/ProcessHandle/PermissionTest.java on macOS, a
few times this error occurs :
java.lang.RuntimeException: Cannot allocate memory

Probably sysctl fails here, but it is not fully clear; it would help to change
the exception so that the standard text is shown too in the exception message.
