        Description


        Eg. this is a snippet of current output from jcmd <pid> VM.native_memory detail

        [0xf6db44f5] SymbolTable::lookup(char const*, int, Thread*)+0xe5
                                     (malloc=22KB #299)

        [0xf6c6e7ff] NativeCallStack::NativeCallStack(int, bool)+0x5f

        [0xf66ca15d] Arena::Arena(MemoryType, unsigned int)+0x14d
        [0xf6c0377d] Matcher::Matcher()+0x4d
                                     (malloc=20KB #2)

        [0xf66cb4a4] CHeapObj<(MemoryType)7>::operator new(unsigned int)+0x84
        [0xf683c7a6] ClassLoaderData::anonymous_class_loader_data(oopDesc*, Thread*)+0x106
        [0xf6dc293a] SystemDictionary::parse_stream(Symbol*, Handle, Handle, ClassFileStream*, KlassHandle, Growabl
        eArray<Handle>*, Thread*)+0xba
        [0xf6e141bd] Unsafe_DefineAnonymousClass+0x5fd
                                     (malloc=19KB #201)

        [0xf6c6e7ff] NativeCallStack::NativeCallStack(int, bool)+0x5f
        [0xf69f54e6] BasicHashtable<(MemoryType)9>::new_entry(unsigned int)+0x166
        [0xf69f5538] Hashtable<Symbol*, (MemoryType)9>::new_entry(unsigned int, Symbol*)+0x18

                                     (malloc=16KB #4)

        It would be nice if these were annotated with mtClass mtCompiler or mtSymbol
