[jira] Created: (IVYDE-132) NPE in
org.apache.ivyde.eclipse.IvyPlugin.getIvy
NPE in org.apache.ivyde.eclipse.IvyPlugin.getIvy
------------------------------------------------
Key: IVYDE-132
URL: https://issues.apache.org/jira/browse/IVYDE-132
Project: IvyDE
Issue Type: Bug
Components: classpath container
Affects Versions: 2.0.0.alpha1
Environment: Eclipse 3.2.2 / Rational v7.0 (pre 7.5)
Reporter: Mladen Maravic
Priority: Minor
Sometimes, IvyDE would cause the following errors to be logged into the Eclipse error log:
java.lang.NullPointerException
at org.eclipse.jface.dialogs.IconAndMessageDialog.getSWTImage(Unknown Source)
at org.eclipse.jface.dialogs.IconAndMessageDialog.getWarningImage(Unknown Source)
at org.eclipse.jface.dialogs.MessageDialog.<init>(Unknown Source)

at org.eclipse.jdt.internal.ui.InitializeAfterLoadJob$RealJob.run(Unknown Source)
at org.eclipse.core.internal.jobs.Worker.run(Unknown Source)
(I've seen instances where line number are present!).
This is due to the fact that the org.apache.ivyde.eclipse.IvyPlugin.getIvy() method uses MessageDialog.openWarning method. MessageDialog uses Display.getCurrent() internally. This results in errors if MessageDialog.openXXXX is used outside of the UI thread.
To correct this, every MessageDialog.openXYZ in getIvy method should be surrounded by this code:
Display.getDefault().asyncExec(new Runnable() {
public void run() {
MessageDialog.openXYZ(.......);
}
});

[jira] Commented: (IVYDE-132) NPE in
org.apache.ivyde.eclipse.IvyPlugin.getIvy
Posted by "Nicolas Lalevée (JIRA)" <ji...@apache.org>.

Nicolas Lalevée commented on IVYDE-132:
---------------------------------------
I already seen that kind of errors, I think every issues regarding display thread has been fixed while the refactoring done with IVYDE-112 and IVYDE-116: now the classpath container is always created without any errors, but it does launch the resolve job that may trigger (handle by eclipse so in the UI thread) some popup errors.
