You can see that I'm not getting an increase in the Netty direct memory size.
Look at
https://github.com/netty/netty/blob/fb5e2cd3aa5644c294905fce3b45c2278f17e15d/common/src/main/java/io/netty/util/internal/PlatformDependent.java#L159
You can see that by default io.netty.maxDirectMemory is == -1 ie netty will
limit its direct memory by using the JVM max direct memory (by defaul should be
== the max heap size IIRC).

> 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]
