I moved the jdbc driver jar out of the ear and into the server target's lib
directory, and I've not been able to reproduce the error in my unit testing
so far.
Is the caching that the 1.4 jvm is now doing a problem for the JBoss
classloader design or is it simply a problem/bug in the jvm itself? If it
is a JBoss classloader issue, is this something that could be fixed?
Especially in cases where Class.forName() is used by the 3rd party code,
even if it's jvm code? I've made sure to use
Thread.currentThread().getContextClassLoader().loadClass("some.Class").newIn
stance() in all of my code, but in some cases it is impossible to know when
a 3rd party lib might be using Class.forName() under the hood.
Thanks again Adrian for the all the excellent support.
