URL: https://github.com/apache/activemq-artemis/pull/3154#issuecomment-636121319
Although it seems like a Netty issue, it's not: the problem is on
`ChannelBufferWrapper` because it's using `UnreleasableByteBuf::readBytes(int
length)` and wrapping its returned `ByteBuf` (which nature depends on the
wrapped allocator) into an `UnreleaeasableByteBuf` that would prevent it to be
released and correctly deallocated.
This PR is both:
- avoiding using an intermediate `readBytes` + `toByteBuffer` to read into a
`byte[]` the data
- removing the wrong method on `ChanneBufferWrapper` given that isn't used
anymore

> Hi,
> It appears that there is memory leak during decompression. Memory used per
> PlatformDependent keeps creeping up until the OutOfDirectMemoryError is
> thrown. Attached is a test program that recreates it. You can see the memory
> creeping up until it runs out. [^ArtemisStressTest.java]
