Hi Bongjae,

my guess is that the same FilterChainContext is used simultaneously by 2
(or more) FilterChains. This may happen when FilterChainContext is
recycled, but still used.
You said it's difficult to reproduce, but is there a testcase, which
fails even if it happens rarely?

Thank you.

WBR,
Alexey.
