[jira] [Updated] (SOLR-5087) CoreAdminHandler.handleMergeAction
generating NullPointerException
[ https://issues.apache.org/jira/browse/SOLR-5087?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Patrick Hunt updated SOLR-5087:
-------------------------------
Attachment: SOLR-5087.patch
This patch fixes the problem by catching/logging/rethrowing the original problem. I've also made some changes to the code to make it less likely that the cleanup (finally clause) will fail.
The test I added fails w/o the fix applied.
This patch applies/passes for me on both trunk and branch4x.

> CoreAdminHandler.handleMergeAction is generating NullPointerException
> If directoryFactory.get(...) in handleMergeAction throws an exception the original error is lost as the finally clause will attempt to clean up and generate an NPE. (notice that "dirsToBeReleased" is pre-allocated with nulls that are not filled in)
