Bug 355541

Comment 1 Remy Suen 2011-08-23 13:27:56 EDT

What JRE are you using?

Comment 2 Felipe Heidrich 2011-08-23 16:41:46 EDT

What version of Windows have the problem ?
Can you write up a simple SWT snippet that reproduces the problem ?

Created attachment 202216 [details]
RCP snipped extracted fom our application

The problematic line of code is located in
"ApplicationWorkbenchWindowAdvisor.java": java.awt.Toolkit.getDefaultToolkit();

Comment 4 Julia Kurde 2011-08-26 06:43:10 EDT

When trying to extract a snipped from our application, we were able to identify the problematic line of code. It is located in
"ApplicationWorkbenchWindowAdvisor.java": java.awt.Toolkit.getDefaultToolkit();

We used this to get the screensize when starting the application to maximize the window on the sceen.

         * It will suppress all tooltips if run on
         *
         * 1) MS Server 2003        2) MS Server 2008
         *    Standard Edition         R2 Standard
         *    Build 3790: SP 2         SP 1 (Build unknown)
         *                             (Excess via CitrixXenApp 6.0 Server 3)
         *   
         * Although tooltips keep visible if run on
         *
         * 1) MS Server 2008        2) Various MS XP PCs
         *    Standard Version 6.0  3) Linux OpenSuse
         *    Build 6002: SP 2      4) Linux Ubuntu
         *   

In the attachment you find the snippet to reproduce the problem.
It could be related to a conflict of awt and swt.

We are using JRE6

See bug 349387.

There are many different versions of Java 6. Which vendor's VM are you using? Which update of Java 6 are you using?

Comment 7 Henno Vermeulen 2011-08-26 07:26:16 EDT

Reproducible under Windows 7 with JDK 1.6.0_26. I am using 3.7 as a target
platform.  Even worse: always seems to happen when deploying an RCP application
through Java Web Start! 

At least one other person has noticed this
(http://www.eclipse.org/forums/index.php/m/693981/?srch=tooltips#msg_693981).

When I simply add Toolkit.getDefaultToolkit() to our
ApplicationWorkbenchWindowAdvisor.preWindowOpen() all swt tooltips stop
working. The weird thing is that all tooltips keep working fine when I only add
this line to postWindowOpen()!

For the Java web start case I suspect that web start calls
Toolkit.getDefaultToolkit() to do some AWT/Swing stuff before starting the
application. (Probably the general web start splash screen and/or the
application splash screen).

Problem does not occur with custom swt tooltip windows
org.eclipse.swt.widgets.ToolTip.

(Wow, I got a "mid air collision"; Remy Suen actually submitted a comment at around the same time :))

Thank you Remy for the bug link, this may well be be a duplicate of bug 355541. 

I tried with an older java version than Sun's JDK 1.6.0_26 and it is not reproducible!

Java 6 Update 26 from Oracle
