Thread dump NetBeans freezing

Hi,

Since I installed Netbeans, it's always freezing at some point after 2 or 3 minutes, often when I'm creating a new files or when I'm changing the focus again on NetBeans. I have to force quit NetBeans, and nothing happen if I'm waiting.

I started with NetBeans 7.3.1 and JDK 1.7u40, I try to upgrade to Netbeans 7.4, it's was a little bit better but still freezing. So, I upgrade the JDK to 1.8 and it's still freezingwithout any reason.

I did several thread dump with jstack, and it's always the same thread in_native and the others blocked.

I think the problem is : 

Thread 1799: (state = IN_NATIVE)
 - sun.lwawt.macosx.LWCToolkit.doAWTRunLoopImpl(long, boolean, boolean) @bci=0 (Compiled frame; information may be imprecise)
 - sun.lwawt.macosx.LWCToolkit.doAWTRunLoop(long, boolean) @bci=5, line=722 (Compiled frame)
 - sun.lwawt.macosx.LWCToolkit.invokeAndWait(java.lang.Runnable, java.awt.Component) @bci=67, line=567 (Compiled frame)

 - sun.lwawt.macosx.CAccessibility.getAccessibleIndexInParent(javax.accessibility.Accessible, java.awt.Component) @bci=15, line=287 (Interpreted frame)

But I'm not sure.

Thanks for your response. (the full last thread dump when NetBeans was freezing is attached.)
