Hi,

I’m looking to understand the situation on the production of full debug symbols, as we’ve noticed at Adoptium jdk26 JDK images no longer have the full debug symbols where they used to be in the JDK image?
For Temurin release builds we use external symbols (--with-debug-level=release --with-native-debug-symbols=external) and then move the JDK debug info files to a separate debug image tarball, I’m trying to figure what we need to change?
Are the images/symbols folder files full debug files? Should we get them from there instead?
 Thanks


Yes, that is correct. The debug symbols are now only put into the symbols image, unless you explicitly configure your build to include them in the regular image and bundles using `--with-external-symbols-in-bundles=full`.

I would also recommend looking at the `make bundles` or `make product-bundles` targets as those will generate the appropriate bundles for you, though on Windows they are zip bundles as that's a more commonly used packaging format for that platform.
