Calling SchemaType.isSkippedAnonymousType() can throw a NPE
-----------------------------------------------------------
Key: XMLBEANS-258
URL: http://issues.apache.org/jira/browse/XMLBEANS-258
Project: XMLBeans
Type: Bug
Components: XmlObject
Versions: Version 2.1
Environment: Java 1.5, Windows XP
Reporter: Luke Peters
Fix For: Version 2.1
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; }
