Cannot reset index state files with latest jdbc driver version 4.2.1.0

Hello,

Before this latest driver patch, I could reset the index files by deleting it. (stop the jdbc driver and then delete the index files in the state directory).

Since version 4.2.1.0 of the driver, it seems the state files are still locked by edir even after the driver stopped.

Does anyone aware of that ?

Or know how to reset the state files ?

thx
