Interesting. Thanks,
Since commons-mail is pure Java, there's no way this can be completely
caused by bugs in commons-mail. though it sounds like some detail in
commons-mail is tickling other bugs elsewhere in the chain. My guess
is the network driver is at fault since that's what crashes and it
only happens in one version of the driver, but it could be the JDK,
the OS, or all three.
