Yes, I can. And I have figured out the issue. The problem is that I create a new .java file with a new class and somehow LR solution project created 2 same file to root and data folder and that caused the access violation... I suspect this would be the issue caused by Eclipse which I use to edit the sources.
Removing the file from data folder fixes the problem.
BTW, I also experience another issue that whenever I update the my .java file in Eclipse that LR and EClipse won't automatically compile to .class. So when I replay the script LR will not execute properly. I have to manually compile it using javac.exe. Any idea to avoid this manual process? Thanks
