Re: svn commit: r191791 -
/james/server/trunk/src/java/org/apache/james/mailrepository/AvalonMailRepository.java
you're right, its the cause ("cause: java.lang.OutOfMemoryError") that is
an OOME
However it is the responibility of the catch in AvalonMailRepository to
delete/not delete the mail,
so I've changed that to use the cause, and not delete the mail for _any_
Error.
This may result in the file leak returning, but only where there are Errors
_and_ orphan files.
I've commited the change for review.

OutOfMemoryError is not a RuntimeException but an Error, isn't it?
The debug was from that code but I think the exception was really a
RuntimeException and not an OutOfMemoryError: it probably was encapsulated
in a RuntimeException before.
Let's read the DEBUG log...
> DEBUG mailstore: Exception retrieving mail:
> java.lang.RuntimeException: Exception caught while retrieving an
> object, cause: java.lang.OutOfMemoryError, so we're deleting it...
> good riddance!
So the "re" caught is a Runtime and is created by the
File_Persistent_Object_Repository with this snippet:
catch( final Throwable e )
{
throw new RuntimeException(
"Exception caught while retrieving an object, cause: " + e.toString()
);
}
I think this patch is wrong (the OOME is not a RuntimeException!). You
should change the File_Persistent_Object_Repository.
