nps Snapshot

nps Snapshot extracted from heap dump. AWT is blocked by "org.netbeans.modules.csl.navigation.BreadCrumbsTask" thread, which has really deep stack traces.
Comment 3 Tomas Hurka 2013-11-21 16:43:36 UTC 
The problem is caused by opening of 549K css file.

Comment 7 Tomas Mysik 2013-11-26 09:56:30 UTC 
Adding "OOM" to the issue summary (perhaps this issue is P2?).
Comment 8 Milutin Kristofic 2013-11-26 12:24:00 UTC 
There are thousands of equal StructureItem objects in css file since CSSRuleStructureItem declares equals just on element name. And file Tomas posted is preparing same structureItems thousand times. Nodes Api is trying to work with equals and it makes this mess. 

I will discuss with Svata, how to fix this.
Comment 9 Martin Balin 2016-07-07 07:32:09 UTC 
This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.

Thanks for your cooperation,
