Bug#1110075: Add more detail about : tomcat9: Regression in 9.0.107-0+deb11u1 breaks startup and applications

[Roland Tapken]

Hello,

> Can you answer to apo about this regression ?

Sorry, I've didn't noticed the question to reproduce this with OpenJDK.
That's not possible as our legacy application still requires Java 8 (that's 
the reason for Temurin).

I suspect that this may be related to a change in the build environment 
for Tomcat and that the .class files may no longer be compatible with 
Java 8 since the release. I will try to set up a test VM and compile 
the packages myself, perhaps that will help me find the difference.

Best regards,

Roland
