Calling SchemaType.isSkippedAnonymousType() can throw a NPE

If isSkippedAnonymousType() is called on a SchemaType instance that does not have _outerSchemaTypeRef set, then a NPE will be thrown. Example:

MyXmlBean myBean = MyXmlBean.Factory.newInstance();
boolean isSkipped = myBean.schemaType().isSkippedAnonymousType(); <- throws a NPE

It seems that it should return false in this instance, rather than throw an exception. All this needs to fix is to add a null check. I'm not sure which versions exactly are effected, but it is an issue in 2.1.

Current code:

public boolean isSkippedAnonymousType()

{ return _outerSchemaTypeRef.get().getBaseType() == this || _outerSchemaTypeRef.get().getContentBasedOnType() == this; }

Potential fix:

public boolean isSkippedAnonymousType()

{ return _outerSchemaTypeRef == null ? false : _outerSchemaTypeRef.get().getBaseType() == this || _outerSchemaTypeRef.get().getContentBasedOnType() == this; }
