idp crash for memory leak?

[Teresa Fasano]

Hi,
yesterday one of our idp has crashed and in the catalina.out I found:

GRAVE: The web application [/idp] created a ThreadLocal with key of type
[org.apache.xml.security.algorithms.SignatureAlgorithm$1] (value
[org.apache.xml.security.algo
rithms.SignatureAlgorithm$1 at 7f3c8e5c]) and a value of type
[java.util.HashMap] (value
[{http://www.w3.org/2000/09/xmldsig#rsa-sha1=org.apache.xml.security.algorithms.i
mplementations.SignatureBaseRSA$SignatureRSASHA1 at 2ee8743c}]) but failed
to remove it when the web application was stopped. This is very likely
to create a memory leak.

GRAVE: The web application [/idp] appears to have started a thread named
[Timer-8] but has failed to stop it. This is very likely to create a
memory leak.

SEVERE: Error while registering Oracle JDBC Diagnosability MBean.
java.lang.NullPointerException

What you think is the reason?
The problem was only resolved after we restart the tomcat.
thanks
Teresa
