LoadComponentFromURL crashes and dies, how to do CPR?

Well I am testing my jython program that does some neat [.xls "," .doc "," .rtf "," .tif "," .tiff "," .pdf "files] -> pdf (intermediate file) → tif (final output) using Open Office Due to automation issues we moved away from MS Office Now it seems we have knocked down a lot of bottles related to showing stop order errors, leaving one bottle. OO freezes after a while.

It happens where you see this line '<<<<<<<<<<<<<<<<in the code

What is the correct way to handle a stuck Open Office process. could you please provide some useful links and give me a good suggestion for an exit.
One more question.

Amount:
* How to handle a stuck Open Office instance?
* How do I do the conversion with java headless so I don't have a GUI that pops up all the time, wasting memory.
* Any general guidelines for code quality, optimizations, and general coding standards will also be appreciated.

Just to clear this exception, only throws when I kill an open office process. Otherwise, the program just waits for the open office to complete. Indefinitely
