I have a Jira plugin I created. I recently updated my Java SDK to Oracle SDK 23 and am now getting a 404 error when I try to load http://localhost:2990/jira/.

Here is the text of the error page I get in the browser:

HTTP Status 404 – Not Found
Type Status Report

Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

Apache Tomcat/9.0.84

And here are the log messages:

I think (but am not sure) that it’s related to Illegal access: this web application instance has been stopped already. Could not load [com.google.gson.GsonBuilder]. However, I haven’t been able to find much on what this actually means. The closest I’ve been able to find is this, which is about a different error message with the same dependency (but doesn’t seem to apply to my case).

In this case, someone was able to resolve a similar issue by shutting down their server and starting it over, but that didn’t work for me.

I saw similar issues here and here on the Atlassian developer forum, but there was no answer to either post.

I already tried running atlas-clean and deleting the C:UsersMyUser.m2repository folders, but neither helped.

I also checked java -version, and everything seems normal there:

java version "23.0.1" 2024-10-15
Java(TM) SE Runtime Environment (build 23.0.1+11-39)
Java HotSpot(TM) 64-Bit Server VM (build 23.0.1+11-39, mixed mode, sharing)

atlas-version seemed ok too:

Can someone point me in the right direction?
