It seems that the adapter is not compatible with Java 6. I made a small change in the PEG.java to make it compilable with Java6 but at runtime I am getting following error:

The Changed PEG.java file is attached for your reference.
PS: I made a change in hurry and that's why resources are not closed. Please ignore that part.

Hi,
By looking at the code it seems to me is that the utility can support all the functionality of the corresponding peg.js file.
Do you see any limitation of the Java adapter in comparison of the peg.js uses?

Thanks,
