Calling size method of a ManageableArrayList causes NullPointerException
------------------------------------------------------------------------
Key: JCR-1053
URL: https://issues.apache.org/jira/browse/JCR-1053
Project: Jackrabbit
Issue Type: Bug
Components: jcr-mapping
Affects Versions: 1.3
Reporter: André Bierwolf
Attachments: NTCollectionConverterImpl.diff
When using the NTCollectionConverterImpl with proxy="true" a call on the size
() method of a ManageableArrayList causes a NullPointerException if there is no
underlying List. LazyCollectionLoader doLoad returns null because there is are
no children.
The ManageableArrayList is created because the isNull method of the
NTCollectionConverterImpl class always returns false.
According to the comment line this is done because the getCollectionNodes
always returns a list.
But after the fix for JCR-882 this is not correct anymore.
The attached fix corrects this.
The only question remaining is how to differ between an empty list and a
null-value for the field containing the list.
