Created attachment 162949 [details] message.log file Similar to various other issues raised. I'm developing against two technology stacks - one project has a Dropwizard (java) backend, with HTML5/Javascript/AngularJS 1 front end in the same project. I've also started a second relavent project with Ionic/Cordova, Typescript and Angular2. Background scanning hangs (one of my 4 CPU's sticks on 100%) on the first project, apparently scanning the HTML5/javascript portions of the project. It won't allow itself to be closed, and has the further impact (I'm assuming) of making operations like 'format code' (in this instance TS code in the second project) hang, present the 'long running process' dialog box, and only allow cancel. Any suggestions? The IDE is suddenly fairly unusable.
Interesting, because it was unusable I just reverted back to 8.1 - (exactly the same projects opened) - and background scanning completes successfully!
messages.log does not show anything unusual. Please capture and attach a .npss snapshot when NetBeans is using 100% CPU. The steps how to obtain .npss snapshot are outlined here: http://wiki.netbeans.org/FitnessViaPartnership Attach also IDE log file (messages.log), which corresponds to .npss snapshot. Thanks.
