The biggest object in the heap dump is an instance of o.n.m.web.webkit.tooling.networkmonitor.NetworkMonitorTopComponent$Model (retained size 187 MB).

Total retained size of instances of class org.json.simple.JSONObject is 194 MB.

Note: The heap size limit is quite low (-Xmx409m).

Reassigning to web/HTML Project. Please evaluate it. Thank you.

Already fixed in 8.0.1. Thanks a lot Jardo for perfect evaluation of the heap dump!
