SEVERE: The web application [/] created a ThreadLocal with key of type [coldfusion.util.DateUtils$1]

We're seeing a large number of SEVERE errors in the logs since updating to CF11,0,02,291725. Always in the following pairs. CF is now crashing about every 10-15 minutes.

We're running on Ubuntu, with external JRE. I reviewed all of SEVERE: The web application [/] created a ThreadLocal - but the errors are slightly different, and notably, a new version of Coldfusion.

SEVERE: The web application [/] created a ThreadLocal with key of type [com.sun.xml.bind.v2.ClassFactory$1] (value [com.sun.xml.bind.v2.ClassFactory$1@30124fd9]) and a value of type [java.util.WeakHashMap] (value [{class javax.xml.bind.annotation.W3CDomHandler=public javax.xml.bind.annotation.W3CDomHandler()}]) 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.

using built-in vs external JRE didn't make any difference. Nor did selectively turning on or off sites running on the server (there's 6 sites, none of which generate high load).

Note: currently investigating issues relating to Solr collections.

Any one seen/experienced this? have suggestions?
