Re: Instrumentation in native code

Prashant,

  This is kinda wrong mailing list to ask such question... but there
is a sample in JDK for bytecode instrumentation in C.

  An alternative approach would be to instrument JRE classes
statically and then prepend those classes to the bootstrap classpath.

  regards,
  Eugene
