Package: tomcat6
Version: 6.0.20-5
Folks,

 Tomcat6 is failing to find some classes for us in valid WAR files on
Squeeze. This has been extensively tested
and works beautifully for us on older revisions of java/tomcat6 (squeeze)
packages back installed on Lenny
and on the current tomcat6 on Ubuntu.

Potentially useful problem information:

I have also run this with both the openjdk and sun java 6, so it's Tomcat's
problem with a very high likelihood.

 I have compiled our JARs with sun 1.5 sun 6 and openjdk, it does not matter
which.

 I have all three installed (as I actually need this in dev/production) but
this also occurs with
just the openjdk.

 Running Jar files have been copied from UBUNTU to Debian to demonstrate
that this is really a debian not a build
problem.

 And of course, it's CRITICAL.

 I have multiple javas installed (due to some packages requiring 1.5 and

You'll see traces like (but I can not provide the jar, sorry):
