PS1: JDeveloper SOA designer bug - hanging expression builder
By clemens.utschig on Nov 12, 2009
Unfortunately we have found a (meanwhile confirmed) bug, that manifests itself in completely blocking your jdeveloper UI due to a race condition between two threads).
This happens if you use the expression builder inside a bpel process, and type a part of an expression, and then use ctrl+space to complete it. Once you start filling in the needed info (e.g. partname), jdev will suddenly block (completely).
Bug 9099332 was filed for this.
Workaround: in jdeveloper -> Tools / preferences / SOA -> uncheck validate expression
