> 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
