[jdktools][jdwp] remove workaround for JVMTI GetStackTrace() problem
--------------------------------------------------------------------

                 Key: HARMONY-2893
                 URL: http://issues.apache.org/jira/browse/HARMONY-2893
             Project: Harmony
          Issue Type: Bug
          Components: JDK
            Reporter: Ivan Popov


There were noticed problems with implementation of JVMTI function GetStackTrace in some JVMs,
it may ignore 'start_depth' parameter and return stack frames always starting from 0. Implementation
of JDWP commands ThreadReference::Frames and StackFrame.ThisObject provides workaround for
this problem by requesting from JVMTI all stack frames and removing not interesting ones from
the list. Though this increases usability of Harmony JDWP agent with different JVMs, it may
negatively affect performance. It makes sense to check how this workaround affect real performance
to decide if it worth to be removed.
