[jira] Created: (UIMA-230) CPE GUI sometimes won't start if JList
widgets are in use
CPE GUI sometimes won't start if JList widgets are in use
---------------------------------------------------------
Key: UIMA-230
URL: https://issues.apache.org/jira/browse/UIMA-230
Project: UIMA
Issue Type: Bug
Components: Tools
Reporter: Adam Lally
Assigned To: Adam Lally
Fix For: 2.1
There's a race condition that can cause a NullPointerException on startup of the CPE GUI. The GUI loads the last known CPE descriptor and attempts to populate the GUI. If there are JList widgets needed (for multi-valued parameters) you can sometimes get a NullPointerException in javax.swing.plaf.basic.BasicListUI.updateLayoutState. Sometimes this error prevents the CPE GUI from starting (other times it is just printed on the console).
Swing isn't thread-safe and I think we aren't doing proper synchronization here.
