Trying to bring up hint
Comment 3 Jan Lahoda 2013-05-09 07:05:24 UTC 
Caused by the fix of bug #228729, which calls GraphicsDevice.getConfigurations(), first invocation of which can take
ages on single-headed Windows.

JDK bug:

Comment 4 Jan Lahoda 2013-05-09 07:50:17 UTC 
Tried preventing invocation of GraphicsDevice.getConfigurations() for single-headed configurations:
http://hg.netbeans.org/jet-main/rev/9b89676e0140

Could someone with Window please test?

Thanks.
Comment 5 Quality Engineering 2013-05-10 00:25:58 UTC 
Integrated into 'releases', will be available in build *201305092200* or newer. Wait for official and publicly available build.
Changeset: http://hg.netbeans.org/releases/rev/d6fe1814d087
User: Jan Lahoda <jlahoda@netbeans.org>
Log: #228729: reverting effects of the fix from the release73 branch, as it is causing a regression in hint popup time (#229200)
Comment 6 Quality Engineering 2013-05-10 02:36:47 UTC 
Integrated into 'main-golden', will be available in build *201305092300* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
Changeset: http://hg.netbeans.org/main-golden/rev/9b89676e0140
User: Jan Lahoda <jlahoda@netbeans.org>
Log: #229200: first invocation of GraphicsDevice.getConfigurations() can be very slow on single-headed Windows, prevent calling it when there is only one GraphicsDevice.
