Fixing up a couple of issues:

  • #143 - toString() didn't work for many of the queues because the default implemetation relied on iterators.
  • #151 fixed by @cliffclick and helped by @vyazelenko - bringing in some fixes and improvements to NHBM
  • Minor javadoc touchups

  • PR #94 : The NonBlockingHashMap by @cliffclick is now released as part of JCTools core. Also thanks to @pcholakov for help is converting and sanity testing some of the benchmark code (PR #108).
  • PR #129 : MPSC linked array queues code is tidied up and split into 3 implementations. The old Chunked is here, but constructor has changed. Growable is split from chunked and Unbounded is added.
  • Bug #135 : Bug fix for the growable MPSC case.
  • PR #127 : Releasing JCTools as an OSGi bundle, thanks @CodingFabian !

  • BUG: SpscGrowable/SpscUnbounded/SpscAtomic/SpscUnboundedAtomic !isEmpty() but poll() == null (Issue #119)

  • Added MpscChunkedArrayQueue an MPSC bounded queue aiming to replace current usage of MpscLinkedQueue in usecases where low footprint AND low GC churn are desirable. This is acheived through usage of smaller buffers which are then linked to either bigger buffers or same sized buffers as queue size demands.
  • Fixed a GC nepotism issue in linked queues. This is not a bug but an observable generational GC side effect causing false promotion of linked nodes because of a reference from a promoted dead node. See discussion here: akka/akka#19216
  • Fixed an inconsistently handled exception on offering null elements. This was a bug in MpmcArrayQueue.
  • Formatting and refactoring
