Description Vladimir Riha 2014-11-23 17:09:34 UTC

Reproducing issue 246598:
Exact steps:
- download ZIP of this project [1]
- create a new HTML5 project for it (set SiteRoot for Project Directory!)
- invoke NPM Install (can end with errors)
- invoke Bower install
- once finished, I left IDE for few minutes in background (switched to browser)
- then I opened PageController.js and typed

util.

and invoked cc. Memory usage jumped to almost 1GB and IDE became unresponsive. Heap dump is available here [2]

Comment 2 Petr Pisl 2015-07-20 08:06:55 UTC

I can reproduce this. My guess is that you pressed CTRL+SPACE twice and invoke code completion for all symbols. I'm going to add an logic, which doesn't allow such queries. Only if there is a some prefix.

Comment 3 Petr Pisl 2015-07-20 10:01:06 UTC

Fixed in web-main. The symbols fro empty prefix are not counted from index.

Integrated into 'main-silver', will be available in build *201507210001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
