The code cache fills up for the test bigapps/Weblogic+medrec/nowarnings. Affected platforms are: linux_amd64, solaris_sparcv9, windows_x64-64, solaris_x64, with tiered compilation both enabled and disabled.
RULE bigapps/Weblogic+medrec/nowarnings Unknown Found warnings in server log: CodeCache is full. Compiler has been disabled. Try increasing the code cache size using -XX:ReservedCodeCacheSize=

The timeout is intentional, by default Aurora stops the test after 30 minutes. I checked and there is a timeout also before the segmented code cache changes were pushed (e.g., the compiler nightlies from 2014-09-15). The only problem that remains to be solved is the code cache filling up too much (the problem addressed by the patch posted by Tobias's). I change the name of the issue accordingly.

The bug is caused by the segmented code cache changes (JDK-8015774). The problem is that with -XX:-SegmentedCodeCache 'CodeCache::reverse_free_ratio' always returns 0 because 'CodeCache::get_code_heap' returns NULL for CodeBlobType::MethodNonProfiled and CodeBlobType::MethodProfiled. I attached a suggested fix.

Interesting. Does this happen only without tiered?
