Comment 2 Ondrej Vrabec 2012-01-27 11:08:12 UTC 
Mercurial opens a file via an OpenCookie, it does not directly call any I/O operations. I would have no problem with calling OpenCookie.open in a background thread if it were not for bug #206861. In that case on the other hand i had to open a form file in AWT because form editor support requires it. So now what, should we call OpenCookie in AWT or asynchronously? Shouldn't this be rather solved inside PropertiesEditorSupport where the file is actually opened?
Comment 3 Ondrej Vrabec 2012-01-31 09:13:21 UTC 
input stream is opened in org.netbeans.modules.properties.PropertiesEditorSupport, probably the support should work asynchronously.
Comment 4 Marian Mirilovic 2012-04-16 13:04:15 UTC 
Increasing priority to P2 - after discussion with performance team and based on the goal for NB 7.2 (performance improvements) especially for remote filesystems.

Removed useless condition. PropertiesDataObject.isMultiLocale returns always false.
