Subject [jira] [Updated] (SOLR-7254) NullPointerException thrown in the QueryComponent
Date Mon, 23 Mar 2015 20:24:53 GMT

     [ https://issues.apache.org/jira/browse/SOLR-7254?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Hrishikesh Gadre updated SOLR-7254:
-----------------------------------
    Attachment: SOLR-7254.patch

Following changes made to the patch

>> Removed redundant validation check in QueryComponent#process
>> Fixed a unit test failure.

[~andyetitmoves] [~yonik@apache.org] Should we commit this change and tackle the (possible)
refactoring (from QueryParser to QueryComponent) as part of a different JIRA?
