My Costomer asked question
---------------------

The trace function is an important feature for Java programmer,
trace function in JVM has the following problems:

 1. It does not support native characters.
    In the trace information several information has a native
    characters, such as string literal,
    variable/class/package/method/thread names.

  Since the trace function does not support the native character,
  it doesn't help so much when we use the native characters in a
  Java program.


  More over, in some context, the JVM took away the first byte of
  the each char type data(UNICODE) we can't convert them to the
  native characters by using trace file taken.

 The JVM should support native characters in it.

 2. Incorrect trace information in the putfield_quick and ldc_quick
instruction.

 The putfield_quick and ldc_quick instruction is putting
 the work area address of the field for its trace information,
 rather than the contents of the field.
 It does not make sense, should output the contents of the field.
