Description

When massive failures with 'did not suspend' error (HARMONY-4631) do not occur, 2 tests fail in EUT 3.2 jdt debug suite with following close error messages:
------------------------------------------
org.eclipse.jdt.debug.tests.core.StepIntoSelectionTests.testStepIntoBinaryMethod

Looks like it can be a regression in JVMTI stepping algorithm.

To reproduce failures:
1) Use Harmony JDK from http://people.apache.org/builds/harmony/snapshots/r576550/apache-harmony-jdk-r576550-windows-x86-32-snapshot.zip
2) Download http://mirrors.nsa.co.il/eclipse/eclipse/downloads/drops/R-3.2-200606291905/eclipse-Automated-Tests-3.2.zip
3) To run with script or command line, use instructions in eclipse-testing/readme.html from eclipse-Automated-Tests-3.2.zip archive
4) To run from Eclipse GUI follow the instruction in http://wiki.apache.org/harmony/Eclipse_Unit_Tests_Pass_on_DRLVM#How_to_run_EUT_individual
