Issue with migrating BPEL from Orace SOA 11g to Oracle SOA 12C - An unexpected Server error has occurred in JDeveloper

Issue with migrating  BPEL from Orace SOA 11g to Oracle SOA 12C - An unexpected Server error has occurred in JDeveloper

Issue:

Trying to migrate some composites from Oracle SOA 11.1.1.5 to 12c. But after I load the project in JDeveloper 12c, its throwing the error "An unexpected Server error has occurred in JDeveloper" and its giving the options like 1)"save all files and exit" 2) Exit without saving 3) continue.

Selected “continue" option and after that tried opening "*.BPEL" file and its completely blank and also all the wires were disappeared from "Composite.xml".

1) Open your SOA project in JDeveloper version 11.1.1.5 and create the SAR ( deployable ) file into your deploy folder. ( Ex: scaSample_rev001.jar )

2) Close the JDeveloper 11.1.1.5 and now open JDeveloper 12c ,

3) File -> Import -> select "SOA Archive Into SOA Project" -> OK -> Next -> Composite Archive Browse to the above SAR file created ( Ex: scaSample_rev001.jar )

4) The composite.xml  and BPEL file will show the content now
