Javadoc of ModelMBeanInfoSupport.getMBeanDescriptor() defines the field 'export=F' as part of the default descriptor.
Extract:

[...]
 The default descriptor is: name=mbeanName,descriptorType=mbean, displayName=this.getClassName(), persistPolicy=never,log=F,export=F,visibility=1 If the descriptor does not contain all these fields, they will be added with these default values.
[...]


But the constructor javadoc for that class defines a default descriptor where field 'export' is gone.
Extract:

[...]
mbeandescriptor - descriptor to be used as the MBeanDescriptor containing MBean wide policy. If the descriptor is null, a default descriptor will be constructed. The default descriptor is: name=className, descriptorType=mbean, displayName=className, persistPolicy=never, log=F, visibility=1. If the descriptor does not contain all these fields, they will be added with these default values.
[...]

The current implementation does not enforce the use of field 'export'.
