[kepler-dev] Kepler RC6 delete bug on Windows XP

[Christopher Brooks]

Hi Chris,
Interesting issue . . .

1. What version of Java are you using?  In Kepler, do Tools | Check System Settings
   and look for "java.version".  I'm running 1.5.0_24 on the Mac.

2. Is this with a clean Kepler from the RC6 installer?

3. Can you replicate it by building the 2.0 branch?
   To build the 2.0 branch, see the Kepler-2.0 instructions at
   https://kepler-project.org/developers/teams/build/systems/build-system/extension-build-system

Looking at the stack trace, we have
org.kepler.gui.KeplerGraphFrame which extends ActorGraphFrame,
which extends BasicGraphFrame.

I looked for duplicates of that those classes but did not find
any.

There could also be something odd with the classpath and classloaders where
the BasicGraphFrame jar file is coming from somewhere outside of the
Kepler-2.0 RC6 tree.  But that seems like a long shot.

To track this down, you could try running Kepler with java -verbose to see
where the classes are being loaded.  I'm not totally sure how to do this,
it would probably require editing build-area/src/org/kepler/build/Run.java
and rebuilding.



Anyway, the offending line KeplerGraphFrame.java is:

   StringBuffer moml = _deleteMoML(graphModel, selection, model);

It has been there awhile:

   KeplerGraphFrame now using BasicGraphFrame's _deleteMoML to fix issue (actually a kepler bug):

I'm not sure what would be causing this.
