Most of problems start with:

java.lang.NoSuchFieldError: fGlobalAttrDeclsExt
	at org.apache.xerces.impl.xs.SchemaGrammar$Schema4Annotations.<init>(Unknown Source)
	at org.apache.xerces.impl.xs.SchemaGrammar$Schema4Annotations.<clinit>(Unknown Source)

	at org.apache.xerces.impl.xs.XMLSchemaLoader.loadGrammar(Unknown Source)
	at org.apache.xerces.impl.xs.XMLSchemaLoader.loadGrammar(Unknown Source)

Then there is one

	at org.apache.xerces.impl.xpath.regex.RegularExpression.setPattern(Unknown Source)

Some of the reports are on IcedTea which may explain why the parser is loaded from org.apache. But I am not sure whether the parser is loaded from JDK or from our own packaged xerces library. Can our XML gurus look at the issue?
Comment 3 Svata Dedic 2012-08-02 13:43:39 UTC 
I probably need more detailed info. I used a fresh 7.1.2 installation, run on OpenJDK  (OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)), then on JDK 1.7 -- no error appeared. Some of the reports show various errors as if the classfile was damaged somehow (verifier errors, truncated classfile), 

I can see that reports from johnny_bit use some custom-built NB installation ? 

Anyway, please provide exact steps how to get the error, provide build numbers of JDK + netbeans, or even download links so I can create matching environment. My system is Linx Ubuntu 64bit, can test on Linux JDKs.
Comment 4 johnny_bit 2012-08-04 09:43:09 UTC 
You see - the problems were random, no steps to reproduce what so ever. I filled reports whether the error appeared. Usually IDE restart was sufficient to fix problem at hand.

About JDK and Netbeans: I use versions provided by Gentoo Linux. Now I am at NB 7.2.
Comment 5 Svata Dedic 2012-08-04 15:26:56 UTC 
OK, please copy your IDE log, there are exact version numbers of both JDK and the IDE + activated modules. If the error happens because of some specific library present (or not present) in your environment, the log would be helful
