Debug Info File not getting associated correctly

Integration

sentry

Java Version

21.0.7

Version

8.16.0

Steps to Reproduce

The build process uses the Maven-Sentry-Plugin with the uploadSourceBundle goal and sets up the jdk properly with correct debug ids in the debug meta of the exception.
The app also uses the log4j2 sentry appender but the tested exception was made with a generic Sentry.captureException.

1. Manually generate source bundle with collected sources in target/sentry/collected-sources (made by the Maven Sentry plugin (the actual uploadSourceBundle goal does the same but bundles less files than found, 900 files found 170 bundled in the case of my project, doing it manually bundles all files))
2. Upload Bundle
3. Add the bundle id to the Sentry.init options
4. Throw a test exception and capture it:

Expected Result

Source code with the exception as seen in the Docs for Source Context

Actual Result

An error with no source code in the Stack trace (both classes are in the source bundle)

And when looking at the images loaded section there is one unreferenced image

which when viewed shows

and opening it in settings shows that there is a file with the correct debug id

It could be i missed something in the docs related to this but i made sure to compare the .jvm files in the .zip and everything seemed in place (.jvm files matching packages with the .java classes) but i found it weird that nothing was showing in the images section

also here's the json of the exception
test-exception.json

If any more information is needed i will happily provide and if it's just that i missed something with my setup please let me know so i can fix my issue.

Hey @Rubyrubex, thanks for the detailed report. We'll take a look tomorrow!
Could you please also provide a link to the issue in Sentry (if you're using our SaaS version, not self-hosted)?
You can do so either here or via email to lorenzo.cian@sentry.io.
Thanks!

• Unrelated: We should explore improve the "images loaded" section because the images will always (even when source context works correctly) show up as "unreferenced" like in your screenshot, which can be confusing.
• Overall, the Maven plugin should work just fine and you shouldn't need to create the source bundle manually like you're attempting to do. Please let me know what isn't working for you with the Maven plugin so that we can fix the bug or consider implementing the missing feature.
• It looks like what you're bundling are the .class files, which won't work. What the plugin bundles and Sentry expects are the .java files themselves (renamed to .jvm, bundled according to the expected format, etc.). You can try bundling those instead. But overall I would prefer if we find what's missing in our Maven plugin (if anything) and fix it.

I suspect you say the Maven plugin is missing some files because it's ignoring the .class files and only bundling the .java ones, which is the intended behavior.

• Yeah the manual bundling was mainly an attempt to debug and understand what was going on
• as for the maven plugin the bundling log shows

  DEBUG   2025-09-30 14:53:57.556800500 -04:00 skipping update nagger because session is not attended

The part i found weird is that it found 924 files but bundled 176 files resulting in the source bundle missing several files including in the case of the test exception the 2 concerned classes
checking the collected-sources directory shows all files being .java

I will also add that the maven command i'm running to build is
mvn clean package
