Norman Maurer 1eabb752c0 Fix NPE that was encounter by debugger (will never happen in real code). (#8992) ... Motivation: We synchronize on the chunk.arena when produce the String returned by PoolSubpage.toString() which may raise a NPE when chunk == null. Chunk == null for the head of the linked-list and so a NPE may raised by a debugger. This NPE can never happen in real code tho as we never access toString() of the head. Modifications: Add null checks and so fix the possible NPE Result: No NPE when using a debugger and inspect the PooledByteBufAllocator.		2019-04-01 19:44:45 +02:00
