The second set consists of stripped debug symbols file called <binary-name>.stripped.pdb which have less information but enough to present line numbers in hs-err files.

The tests for runtime linking will now, in the absence of jmod files, pick up the .pdb files (without *stripped*) from images, but in the runtime the hashes of the *stripped* files are stored.

Jmods and Bundles still contain the stripped pdb files and we also fix the issue that the debug symbols bundle also contained stripped pdb files so far. With this fix, it will contain the full pdb files and extracting these over a JDK runtime will replace stripped pdbs with full pdbs.
