Description

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?
