Hi,
I got following warning after stopping my context with Tomcat 6.0.29
01.02.2011 15:58:00 org.apache.catalina.loader.WebappClassLoader
clearThreadLocalMap
SCHWERWIEGEND: The web application [/myapp] created a ThreadLocal with
key of type [null] (value [com.MyClass$1@7cef53]) and a value of type
[org.apache.commons.codec.net.URLCodec] (value
[org.apache.commons.codec.net.URLCodec@445c74]) but failed to remove it
when the web application was stopped. This is very likely to create a
memory leak.
I searched in this list and found some answers saying that these
messages with "key of type [null]" are false positives.
This should have been fixed in 6.0.25 according to these posts and
according the relase notes:
"Modify ThreadLocal memory leak detection to not report false positives
and to simplify implementation. (markt/kkolinko) "
The corresponding lines in myClass are:
private static final ThreadLocal<URLCodec> sURLCodec = new
ThreadLocal<URLCodec>() {
protected URLCodec initialValue() {
return new URLCodec();
}};
Is this a false alarm or wrong usage?
Regards,
Michael
