I used to work on JDeveloper 11.1.1.1.0 and had a project all set up.
I installed a new PC (64-bit machine) and a new JDeveloper (11.1.2.3.0) and wanted to run my existing project on it. When porting the project to the new JDev i was asked if i wanted to migrate the existing files to the new JDev format and i clicked on 'Yes'.
Upon compilation, I got no code compilation errors. However, the compilation failed due to this error: "Error: An unreported error occurred in Appc. No errors were reported, but the tool returned a failure result code: 1. "
I turned on verbose mode, but couldn't get any additional messages that indicate what the problem might be. I've seen a series of threads where people discuss similar problems, but no-one ever mentioned if he/she resolved the issue.
Some information about my system:
JDeveloper version: 11.1.2.3
java.version: 1.6.0_45
java.vm.info: mixed mode
java.vm.name: Java HotSpot(TM) 64-Bit Server VM
java.vm.version: 20.45-b01
Let me know if more information is needed and thanks in advance.
