An illegal reflective access operation has occurred

About 5.3.77-nginx: While starting tomcat and lucee as non root.

That's resolved with the latest, felix.framework-6.0.3? http://svn.apache.org/repos/asf/felix/releases/org.apache.felix.framework-6.0.3/doc/changelog.txt

Check, today's lucee.jar-5.3.5.3 Snapshot has felix version 6.0.2.

Please update LDEV-2300 as well ;-) https://luceeserver.atlassian.net/browse/LDEV-2300

Can you try the lucee/lucee:5.3.5.3-SNAPSHOT tag? Each commit has a snapshot build so that you can try the bleeding edge commits :)

I am not able to reproduce this issue at local machine. But if i build and check /usr/local/tomcat/logs/catalina.out from lucee:5.3.5.3-SNAPSHOT, it's still there.

[justincarter]

The WARNING is still there in the latest build (5.3.4.77);

However the error that you were getting (ERROR: Error creating bundle cache.) isn't present. There doesn't seem to be any negative side effects other than the warning at this time. Do you think there's anything else we should look at to try to resolve this?

[jamiejackson]

I'd prefer if we could get rid of the warnings; otherwise, one has to keep an inventory of "ignorable" errors/warnings when troubleshooting, updating Lucee, etc.

Otherwise, you have thoughts like:

• Did my latest release / lucee upgrade cause this error/warning, or was it there before?
• Does it matter? Let me go spend some cycles researching/remembering if I can ignore this or not.

[justincarter]

Agreed.

At this time I don't know of a way to remove the warning though, see; https://luceeserver.atlassian.net/browse/LDEV-2300

I'm not sure if Lucee can suppress the Felix warning, but it seems like an upstream issue more than a Docker image issue?

[cybersonic]

This happens whether in docker or not. Since there is already a ticket for it in the main lucee repo, we can close this ticket.
