We do expect the debuginfo files to be reproducible and hence free of absolute paths. This was implemented in https://bugs.openjdk.org/browse/JDK-8284437, where `-fdebug-prefix-map` was one of the mitigations applied. I would start my investigation with trying to understand why that option isn't working, or being applied, when you build with `--enable-ccache`.
