Description mikewr 2008-10-16 22:30:23 UTC 
When editing a Composite Application using a recent Open ESB nightly build (or using GlassFish ESB MS1 or MS2) sometimes
the scrollbars start to blink.  This usually happens after resizing the IDE window to be wider or when resizing the left
navigation window narrower or the right side property sheet narrower.

When the scrollbars blink, the system monitor shows the CPU pegged at 100% and the IDE responds very slowly.

I haven't seen this problem on Windows, only on Ubuntu Linux so far (Ubuntu-8.04-desktop-i386)

Workarounds: close the .casa editor window, or select a different tab, or resize the editor panel to be narrower (or use
a different OS). 

Impact: makes it very hard to develop screencasts for blogging about SOA (using my preferred Linux development system).

I can confirm the same behaviour running NetBeans 6.5 RC1 on LinuxMint Elyssa (an Ubuntu 8.04 derivative). Here is my
Help/About info:

Product Version: NetBeans IDE 6.5 RC1 (Build 200810171318)
Java: 1.6.0_10-rc2; Java HotSpot(TM) Client VM 11.0-b15
System: Linux version 2.6.24-16-generic running on i386; UTF-8; en_GB (nb)

Tentative diagnosis: It looks like a window resizing loop. A window calculation is made which causes scrollbars to be
added, which triggers some resize event which itself triggers a size calculation, as a result of which the scrollbars
are removed.  And round it goes again.

If I drag the splitter between the JBI Modules and the External Modules almost all the way to the right, I can stop 
this behaviour.
