> There is memory-leak bug in snappy-java 1.1.1.4/5, we should rollback to
> 1.1.1.3 or wait for bugfix.
> The jenkins tests timeouted or OOM multiple times recently. While test it
> locally, I got the heap dump of leaked JVM:
> Then found that it's a bug in recent releases of snappy-java:
> {code}
> + inputBuffer = inputBufferAllocator.allocate(inputSize);
> + outputBuffer = inputBufferAllocator.allocate(outputSize);
> {code}
> The outputBuffer is allocated from inputBufferAllocator but released to
> outputBufferAllocator: https://github.com/xerial/snappy-java/issues/91
