I'm pretty sure that arguments and locals aren't there.  Well, maybe
some JVMs include them, but java.lang.StackTraceElement has no methods
to access them.  It must already be expensive to fill in the limited
stacktrace that is present in Sun's JVM so maybe it would be possible to
include them.  OTOH, a hacker could walk the stack to find security
holes.
