It looks like Aqua L&F bug.
The class javax.swing.plaf.basic.BasicHTML$Renderer has 20K instances and consumes 426Mb of memory.
The class com.apple.laf.AquaTabbedPaneContrastUI holds BasicHTML$Renderer.
Reassign to evaluation.

Comment 3 Svata Dedic 2016-12-08 09:42:50 UTC

Agree that the renderers are for some reason (= unnecessarily most probably) held by the TabbedPaneContrastUI, but  is referenced from core's I/O window implementation.

This bug seems already to be reported to JDK team - see https://bugs.openjdk.java.net/browse/JDK-8017284
According to JDK bugtrack system, it was fixed 3 years ago in JDK9 sources. 

Will not fix in NB sources. Reassigning to appropriate component.
