Subject [jira] Created: (SOLR-2357) Thread Local memory leaks on restart

Thread Local memory leaks on restart

                 Key: SOLR-2357
             Project: Solr
          Issue Type: Bug
          Components: contrib - Solr Cell (Tika extraction), search
    Affects Versions: 1.4.1
         Environment: Windows Server 2008, Apache Tomcat 7.0.8, Java 1.6.23
            Reporter: Gus Heck

Restarting solr (via a changed to a watched resource or via manager app for example) after
submitting documents with Solr-Cell, gives the following message (many many times), and causes
Tomcat to shutdown completely. 

SEVERE: The web application [/solr] created a ThreadLocal with key of type [org.
apache.solr.common.util.DateUtil.ThreadLocalDateFormat] (value [org.apache.solr.
common.util.DateUtil$ThreadLocalDateFormat@dc30dfa]) and a value of type [java.t
ext.SimpleDateFormat] (value [java.text.SimpleDateFormat@5af7aed5]) but failed t
o remove it when the web application was stopped. Threads are going to be renewe
d over time to try and avoid a probable memory leak.
