Does Oracle release patch to fix bugs for JDeveloper? I am using JDeveloper 188.8.131.52. I encountered few issues. For e.g.
Jan 17, 2013 11:39:12 AM oracle.ideimpl.index.ProjectTracker$ProjectListener invokeListener
SEVERE: Exception in FileChangeListener oracle.bpm.fusion.repository.fs.FusionFileSystem$1
java.lang.IllegalStateException: Multiple objects with component type 'xml' and id 'F|http://Svc.com/SoapSvc/|InvalidRqstFault|http://Svc.com/SoapSvc/|SoapSvc_Enrollment_InvalidRqstFault_FaultMessage' have been found on the index
when I created a web service adapter to consume a web service. This works fine in JDeveloper 184.108.40.206.
You would need to log an SR with Oracle support https://support.oracle.com/ , needless to say you would need valid support contract with Oracle too.
Why cnt you migrate to 220.127.116.11 though since its the latest release ?
