-------------------------------------

             Summary: CacheLIRS returns null value
                 Key: OAK-1468
                 URL: https://issues.apache.org/jira/browse/OAK-1468
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: core
    Affects Versions: 0.17.1
            Reporter: Marcel Reutegger


While running some test I see the following NPE:

{noformat}
Caused by: java.lang.NullPointerException: null
	at org.apache.jackrabbit.oak.plugins.document.DocumentNodeStore.readChildren(DocumentNodeStore.java:629)
	at org.apache.jackrabbit.oak.plugins.document.DocumentNodeStore$3.call(DocumentNodeStore.java:589)
	at org.apache.jackrabbit.oak.plugins.document.DocumentNodeStore$3.call(DocumentNodeStore.java:586)
	at org.apache.jackrabbit.oak.cache.CacheLIRS$Segment.get(CacheLIRS.java:841)
	at org.apache.jackrabbit.oak.cache.CacheLIRS.get(CacheLIRS.java:212)
	at org.apache.jackrabbit.oak.plugins.document.DocumentNodeStore.getChildren(DocumentNodeStore.java:586)
	... 25 common frames omitted
{noformat}

The NPE shouldn't be possible there, because the Callable implementation returns a non-null value (unless I'm terribly mistaken). The hasMore flag of the returned Children object is set before each of the returns statements in DocumentNodeStore.readChildren().

Please note, this happened with a previous version of Oak where the default cache implementation was CacheLIRS. Right now, the DocumentNodeStore uses the Guava implementation per default.
