-------------------------------------------------------------
There are two directions to narrow down the problem:
1) simplify the query until removing anything from it the problem will gone
2) remove the customized configurations (for example, extraJavaOptions), until
remove anything of them the problem will gone.
This could be a critical bug, hopefully we could find a way to fix it.
