A DESCRIPTION OF THE PROBLEM :
Upon execution of an application of a Java applet involving a network communication operation,
From JDK 8u40 onwards, memory consumption of the JVM process increases with the passage of time, a memory leak has occurred.
This phenomenon does not occur in Java SE 8u 31 or earlier environments.
As a result of investigating using the Native Memory Tracking function,
We are confirmed that this phenomenon is occurring by continuing the expansion of the area of ������Thread arena.
The size of the Thread arena area is about 30 KB immediately after starting, but it continues to increase about 3 MB in 24 hours.
The applet is running with the Internet Explorer 11 plugin.

This issue reminds me of JDK-8164293 which also has similar problem leaking in native memory as reported continous expansion of thread arena. JDK-8164293 issue is fixed in 8u152 requesting submitter to verify on 8u152 ea build could bring more light on this.

Reported with 8u111 as affected version, the Java applet used in Network communication operation seems consuming more memory stating with version 8u40 and above. We need detailed information including a reproducer to investigate this issue better. Therefore, written back to the submitter requesting additional information with status with current version 8u121 and 9 ea.
