--------------------------------------
Summary: FileUtil.getDefaultTempDir() causes a classloader leak in
webapps
Key: CAMEL-6452
URL: https://issues.apache.org/jira/browse/CAMEL-6452
Project: Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 2.10.4
Environment: tomcat 7, spring 3.2
Reporter: Sanjay Deshmukh
FileUtil.getDefaultTempDir() registers a JVM shutdown hook to delete the
temporary directory it creates. We are using camel in a web application in
Tomcat that gets dynamically reloaded as updates are available, so the JVM is
normally never shut down. This is causing 'camel-tmp-*' directories to linger
in $CATALINA_HOME/temp, and - more importantly - classloader leaks, which are a
major problem for us.
If the thread that gets registered as the shutdown hook were stored in a class
variable, I could unregister it when the application is being unloaded.
