[jira] Commented: (FELIX-1845) Unclear exception being thrown:
java.lang.ArrayIndexOutOfBoundsException: 0
[ https://issues.apache.org/jira/browse/FELIX-1845?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12773922#action_12773922 ]
Geert Schuring commented on FELIX-1845:
---------------------------------------
I've found the cause of the exception! It's a file called package-info.java. I've attached it to the issue.
I think the SCR plugin lacks a null check after reflecting the contents of the java source file which only contains a package declaration and no class.
