Hello,

I could see similar logs in Production(using version 1.62), Is this a major issue? any fix planned for this ?

SEVERE;WebappClassLoader#clearReferencesThreads;The web application [/xyz/axis2] appears to have started a thread named [Thread-9] but has failed to stop it. This is very likely to create a memory leak.
SEVERE;WebappClassLoader#checkThreadLocalMapForLeaks;The web application [/xyz/axis2] created a ThreadLocal with key of type [org.apache.axiom.util.UIDGenerator$1] (value [org.apache.axiom.util.UIDGenerator$1@1db13b]) and a value of type [long[]] (value [[J@15ebc73]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.
