No worries, it should be rather me to not get to this earlier....

> @tschatzl I like your proposal of fixing the GC implementation directly, as mentioned in my PR description it was my favorite option but because I found that this bug existed for at least Parallel GC and G1 I wanted to have something in CodeCache directly to ensure we never have an issue related to GC implementation. I had a look at your commit and feel like it is the good direction for G1. Thank you for having a look at it

First, I assume you verified my change ;)

How do we proceed from here? Do you want to reuse this PR or should we (I, you?) open a new one for the new suggestion?

What do you prefer? I am fine with either option.

Thanks,
  Thomas
