1. Open attached free-form project.
2. Open context menu and go to Properties >> Java Source Classpath >> Java Platform and change JDK platform from 1.8 to 1.7.
3. This exception is thrown.
4. Open context menu again and JDK plataform is set back to 1.8.
5. Go to Java Source and change the Source Level to 1.7 or 1.6.
6. This exception is thrown.

Workaround: None that I know of.

Project to use for reproduction.
Comment 4 Tomas Danek 2013-10-08 08:20:51 UTC 
It's reproducible just by changing project source level to 1.8. This forces use of http://netbeans.org/ns/freeform-project-java/4.xsd; any further downgrade of source level throws exception.

Workaround is easy: change you project.xml manually:
change 
<java-data xmlns="http://www.netbeans.org/ns/freeform-project-java/4">
to
<java-data xmlns="http://www.netbeans.org/ns/freeform-project-java/3">

and 
<source-level>1.8</source-level>
to 
<source-level>1.7</source-level>
Comment 5 MackSix 2013-10-08 15:53:25 UTC 
How am I supposed to change Java Platform to 1.6?
Comment 6 MackSix 2013-10-08 16:01:00 UTC 
I can't even change Java Platform from one version of JDK 7 to another now after changing the source level entries in project xml. I was able to do it a couple of times and now it throws the exception and won't change.
Comment 7 MackSix 2013-10-08 16:03:23 UTC 
I rebooted NetBeans and it now allows me to change Java Platforms between different JDK 7 versions again.

Plus you may have to Reboot NetBeans to allow the Java Platform to be changed from 1.8 to 1.7, between 1.7 versions or a 1.6 version.
Comment 9 MackSix 2013-10-08 17:19:39 UTC 
If I have JDK Platform set to JDK1.6.0_45 and try to change source level to 1.5, it throws this exception too.

jlahoda: there's an duplicate issue that you had assigned to yourself?
Comment 11 MackSix 2013-11-15 18:59:49 UTC 
I can't believe this isn't a patch1 candidate. ;)

stacktrace

This is a FreeForm Java project.  I was trying to add and remove jars from the Project Properties src class path.
The last time I did this, it forgot my new settings and reverted back to the old ones.
This was more or less the first thing I did when I started up NetBeans.  The project was already opened.
