Hi Thomas, sure we can try that.
I covered only AIX in this PR, because we observed issues with bad dll/thread stack trace output on AIX, but so far not on Windows.
E.g.  in some fontconfig related crashes, see here for details
https://bugs.openjdk.org/browse/JDK-8314152
8314152: libfontconfig missing on AIX in many hs_err 'Dynamic libraries' lists and native stack incomplete

 the dlopen operations coming from the JDK codebase are just not covered for some time until the next cache update happens, so we have a timeframe with outdated info that leads to bad output.
