File left locked after exception during init #18

Open GoogleCodeExporter opened 8 years ago

Hello,

You need to make sure that you close all locked files in RecordFile
as if the file is corrupted a Throwable is raised on init and a lock on teh 
file is kept from RecordFile - e.g. no way to delete the file pragmatically 
after this type of Exception ( Throwable )

Exception in thread "main" java.lang.InternalError: Unknown serialization
