[jira] Commented: (ARIES-501) NPE in Aries JNDI when trying to
process an empty service list
[ https://issues.apache.org/jira/browse/ARIES-501?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12935986#action_12935986 ]
Alasdair Nottingham commented on ARIES-501:
-------------------------------------------
If no references are found OSGi gives us back a null array of ServiceReferences which we then merrily dereference in the hasMoreElements method. Simplest fix is to make sure ServiceReference[] is not null.
