It is low priority since it is only debugging issue.

I got next failure when a method bytecode is printed:

% gamma jnt.scimark2.commandline
CompilerOracle: print jnt/scimark2/Random.nextDouble

#  Internal Error (src/share/vm/interpreter/bytecodeTracer.cpp:484), pid=4013, tid=1
#  Error: ShouldNotReachHere()

I think, it is because the next line was removed in 6655646 changes in

 void BytecodePrinter::print_attributes(Bytecodes::Code code, int bci, outputStream* st) {
   // Show attributes of pre-rewritten codes
-  code = Bytecodes::java_code(code);
   // If the code doesn't have any fields there's nothing to print.

Bytecode is:

[t@1 l@1]: print code
code = _fast_aaccess_0
[t@1 l@1]: print Bytecodes::java_code(code)
Bytecodes::java_code(code) = _aload_0

The code passed when I restored the line.
