Issue:

When attempting to start the Diagram Trace Utility (DTU) it fails and the following error message is produced:

!ENTRY org.eclipse.core.resources 2 10035 2017-12-02 18:54:31.715
!MESSAGE A workspace crash was detected. The previous session did not exit normally.

!ENTRY org.eclipse.osgi 2017-12-02 18:54:31.715
!MESSAGE An error occurred while automatically activating bundle
org.eclipse.core.resources (14).
!STACK 0

org.eclipse.core.internal.compatibility.PluginActivator.start() of bundle 
org.eclipse.core.resources.
...
Environment:
Windows
Resolution:

This is usually caused by a corruption in the DTU workspace files as result of a previous crash. The simplest way to correct the problem is to force the DTU to create a new workspace as follows:

  1. Go to directory C:\Documents and Settings\<USERID>\DiagramTraceUtility
  2. Rename directory workspace to workspace_bak
  3. Restart the DTU. A new workspace directory should be created.
