I wrote a simple program. just a CTabFolder and a WelcomTab inherent from CTabItem. I want to fill my WelcomeTab by a browser which render my htmls. at the init() method of WelcomeTab I Create a Browser but when program want to construct it I get this Error
Exception in thread "main" org.eclipse.swt.SWTError: No more handles [Unknown Mozilla path (MOZILLA_FIVE_HOME not set)]
at org.eclipse.swt.SWT.error(Unknown Source)
at org.eclipse.swt.browser.Mozilla.initMozilla(Unknown Source)
at org.eclipse.swt.browser.Mozilla.create(Unknown Source)
at org.eclipse.swt.browser.Browser.<init>(Unknown Source)
at org.hekmatof.Hbook.UI.WelcomeTab.init(
at org.hekmatof.Hbook.UI.WelcomeTab.<init>(

in addition I Use Eclipse 3.7 on KDE based on Arch-Linux
as I searched for this Error everywhere tells about handle limited on threads, but this is simple program with no Font or Image ... to dispose. I think it should be a problem about gain handle from Operation System. Could it be a bug? or I'm wrong?

The command
apt-get install libwebkitgtk-1.0-0
removed the error for me.

If you are using a 32-bit Eclipse (with a 32-bit JRE) on a 64-bit Linux, you need to install the 32-bit variant of the webkitgtk libraries:
sudo apt-get install libwebkitgtk-1.0-0:i386

Without the suffix, it would install the 64-bit webkitgtk libraries, which a 32-bit JRE cannot use.
