In the context of 424340 we faced a NPE in DisabledResourceManager.save()

java.lang.NullPointerException
	at org.eclipse.wst.validation.internal.DisabledResourceManager.save(DisabledResourceManager.java:67)
	at org.eclipse.wst.validation.internal.DisabledResourceManager.disableValidation(DisabledResourceManager.java:49)
	at org.eclipse.wst.validation.ValidationFramework.disableValidation(ValidationFramework.java:130)
	...

This happens if a disabled resource is deleted. The resource still remains listed in the "disabled" preference. After Eclipse is restarted, the "disabled" preference is deserialized in DisabledResourceManager.load() and the deleted resource cannot be resolved to an existing resource in the project. This results in adding a "null" object in the "_disabled" set, which causes NullPointerException on consecutive save operations.

I just noticed that this is duplicate to bug 399121, which was fixed in 3.5. I had 3.4.2 in my target platform.
