Have been getting a similar error. Tried restarting the machine, but it did not help. No idea as to what this error means.

I've had similar issues and not sure what causes it - I think it is when I have a few projects open at the same time, editing and saving projects - some stuff seems to disappear from the .uip file!

For example, I do my build installs on UNIX so when I opened my project and built it - I had the same problem as ketan_karnick. When I CLICKED on the "Product Uninstaller JVM Resolution" in Application Data->Launchers->click the Advanced View on the bottom->Product Uninstaller-> Product Uninstaller JVM Resolution - I was getting JVM errors in my xterm window!!!! Thankfully - I had a backup of my project and when I did a diff on my 2 files, the whole JVM uninstaller section was missing from my .uip file!!! I basically closed my project and manually added the section to my .uip file!

This has happened to me in a couple of other different areas of the .uip file, usually will get an array error or something! You can usually find out where in the project the error is from - at least when I'm on UNIX, when I've clicked on say a component, my GUI didn't open the component and I got messages to my Xterm window - not sure what the Windows one does, but then I looked in the .uip file and went to the component I could see that for example, there were 3 files added to a files action and the components array value was showing 1!

If you do not have a backup, you can open up another project and go to the Uninstaller section and copy the Uninstaller section - for the most part they should all be the same for your products!
