I'm trying to build a cut down version of the Ext All library by commenting out unwanted components in a copy of the ext.jsb2 file.

I've tried to comment out lines using // and /* */, but this results in errors when you attempt to build:

PHP Code:
Missing value at character 26375
Failed to open project file
.
java.lang.NullPointerException
        at com
.extjs.JSBuilder2.createTempHeaderFile(JSBuilder2.java:141)
        
at com.extjs.JSBuilder2.main(JSBuilder2.java:38)
Failed to create temporary header file.
....
more snipped... 
Can lines be commented out, or do they have to be removed?
