Java memory leak in native internal area
<p>My application (Spring+Tomcat) on openjdk8u66 leaks in internal native memory. Heap GC behaves properly. 
Ex. Xmx=4g. in some time heap still has the same limits, but process memory increased to 6G</p>

<p>With <strong>jcmd</strong> util i've made <strong>summary.diff</strong>  and find out that <strong>Internal</strong> section of result grows +905MB. What is stored there and is there a way to go futher with my investigation?</p>
