Happens intermittently on all platforms. The stacktrace:

Java HotSpot(TM) 64-Bit Server VM warning: CodeHeap 'non-profiled nmethods' is full. Compiler has been disabled.
Java HotSpot(TM) 64-Bit Server VM warning: Try increasing the code heap size using -XX:NonProfiledCodeHeapSize=

Slightly modified code snippet:

   // type is a BlobType.MethodProfiled
   MemoryPoolMXBean bean = type.getMemoryPool();
   int size = (int) (bean.getUsage().getMax() >> 7);

No usage object initialised for the said MemoryPool?
