Hello,
we have Tomcat 9.0.96 and Java 8.
We would like to get rid of Oracle java and use IBM semeru.
Can Oracle java simply be replaced by ibm semeru,
Yes.
or are changes to the java and jsp applications necessary?
No.
Do the java libraries we call from our jsp-pages have to be recompiled?
No.
The only caveats to the above are:
If your application uses any non-public Java API (usually via
reflection) there is a small risk it will break.
Likewise for the places where Tomcat does this (from memory just the
memory leak protection and that can be disabled if it is an issue)
There is a small risk you find a JRE bug you didn't see with Oracle.
Overall, all of those risks are very small. I'd expect it to just work.

Hello Mark,
I made some more test, but it works only for a few clicks, then the
service stops. It's running on windows ( for reasons I dont'know and
can't change)
with semeru 17 I see this lines in the logs
