Summary: Argument type mismatch after redeploy
Initial Comment:
Bug:
Deploy hello.jar, then undeploy, then redeploy it
again.
After the redeployment calling the hello method
with a string parameter still works, but passing
a HelloData instance as parameter in the howdy()
method results in an IllegalArgumentException:

Default config
OS-System: Windows NT 4.0,x86
This happens on Windows NT as well as on Solaris.
(On Solaris removing the jar during undeployment works,
on WindowsNT never).
The only way I have found to get around this
is to restart the server.

With the latest changes to unique the tmp/deploy file
copied in from the original, the class loaders dumped out
at the time of exception now show a difference:

The HelloData class is not seen to be an instance of the
bean method's argument signature type even though they have
the same class loader instance. If I catch the
IllegalArgumentException and dump out the ejb method sig
classes and classloaders they match the incoming argument
data, and yet, the arg data is not seen to be an instance
of the signature class.

I think this is the "remote" version of the problem with
classloaders seen in 516684 and 519699. If so it should be
fixed only when we run on jbossmx. Any other opinions?

The easiest way to reproduce this error is to
run the test suite a second time without restarting
the server. After the second run has completed:
testsuite\output\log>grep -n IllegalArgumentException
*.log|wc -l
10
Some BeanUnitTestCase suffers from the same problem.
This really gives me the breaks with JBoss, because
I have to restart the server each time I need to
redeploy an EJB.
Any ideas? Any help?
If someone is willing to point me in the right direction
I'll attack this myself (have to), but currently
I have no clue what could cause these exceptions.
(I've been working all day with JBoss
for the last two and a half month, making transitions
from 2.4.4 to 3.0alpha to 3.0beta. Now that my project
is approaching production mode, JBoss seems kind of messed
up.
And the 3.0alpha from the first half of January looked
so good... but with all the changes in jbosscmp-jdbc.xml
I could not go back even if I had a backup
of that version.
Sigh.
Georg
