Java EPMD server memory leak

[xxlabaza]

Netty server reports about a memory leak during benchmark testing in an encon-java lib.

How to reproduce:

0. clone encon-java project:

$> git clone https://github.com/appulse-projects/encon-java.git

1. go to the root of encon-java project:

$> cd encon-java

2. run JMH benchmark tests like this:

$> mvn clean package \
     -DskipTests \
     -Dgpg.skip \
     -Dfindbugs.skip=true \
     -Dpmd.skip=true \
     -Dcheckstyle.skip \
     -Dmaven.test.skip=true \
     -pl benchmark -am; && \
   java -Xms1G -Xmx2G -jar benchmark/target/benchmarks.jar

3. during the tests, you will see something like this:

Possible sollution:

You need to investigate the Netty's report properly and maybe rewrite the EPMD server's handler(s).

You can take a look at Encon's implementation for handling clients requests
