Hi, thanks. I agree that this is a general Java issue in any
application using serialization - the vulnerability attack vector
would just move to less common libraries (we point this out in the
release notes).
Also I must admit for me it was a bit confuising at first to learn
about how a scripting language could be used to run arbitrary code -
well that's the point! :-)  However the issue could arrise just by
bsh.jar on the classpath and doing any other kind of deserialization
from files or the network.

Patrick Niemeyer (CC) did the license change as part of the code
donation to ASF:

Pat is also part of the https://github.com/beanshell team.

I've added a brief History section to
https://github.com/beanshell/beanshell#history - perhaps Pat want to
review that :)

We changed the groupId for 2.0b5 as it was unclear at the time what
was the relationship with beanshell.org, and also beanshell.org also
had an existing 2.0b5 release under LGPL.

Since Google Code shut down http://apache-extras.org/ as a domain name
has become a bit meaningless, so now org.apache-extras.beanshell is
not a good groupId.

We could probably change the groupId back to org.beanshell and as a
GitHub project take over management of the http://beanshell.org/
website - but there's a bit of legacy to maintain there (e.g. older
releases and Beanshell 1) - so that's up to Pat to decide - perhaps
just a banner pointing to the GitHub page would be enough?

I've added https://github.com/beanshell/beanshell/issues/17 to discuss this.

There is also the fork https://github.com/pejobo/beanshell2 - but
pejobo has also joined https://github.com/beanshell so hopefully his
patches there would move across. (They have to be recontributed by the
original authors as beanshell2 was LGPL)
