Re: [bdbxml] Crash in dbxml_javaJNI.XmlResults_next__SWIG_0

Thomas,

I see one problem in the program.  Your run() method is
open/closing the manager and container upon each iteration.
This will not work in the presence of threading, and is
not recommended, in general.

You should share a single XmlManager and open XmlContainer
object among threads, and only close when the application is
exiting.

Regards,

George
