I’m in process of migrating to a newer version.
After upgrading from I can find following error in the JVM log. Below this entry, no further lines are written.

Don’t forget to tell us about your stack!

OS: Windows Server 2016
Java Version: Adopt JDK 11 (fails on 8 as well
Tomcat Version: Caucho Resin
Lucee Version: Fails on all testet version >

Which version are you upgrading from?

Do you have any third party jars?

@Micha11, Did you update the lucee from admin? OR just downloaded and paste that jar?

If you put that jar as manually means, we’ve to put under the \resin-pro-4.0.65\webapps\lucee-\WEB-INF\lib.

But, I can’t sure why it’s there ( C:/resin-pro-4-2/lib/lucee- ) as per your stacktrace.

And I’ve checked and updated from to latest with using Caucho Resin too. Its works fine for me. I didn’t get any issue. Please check and report here.

The last running version is

I have my Lucee at C:\resin-pro-4-2\lib\lucee-, which is the version I initially installed.
At C:\resin-pro-4-2\lib\lucee-server\lucee-server\bundles\ I have log4j-1.2.17.jar

The updates were installed from the Server-Admin, as far as I remember without errors.

I cannot remember installing third party jars.

Is it usefull to remove the old lucee.jar and lucee-server directories and download a new one, so it get freshly extraceted?
