SaxonWebService and other webapps use perm gen space

[joshuadf]

When redeploying webapps, in some (many?) cases the ClassLoader created for the old deployment still references some objects and so will never be garbage collected. This eventually makes Tomcat throw java.lang.OutOfMemoryError: PermGen space .

• ​Tomcat FAQ: Deployment
• ​Memory leaks where the classloader cannot be garbage collected
• ​Explaining and Fixing java.lang.OutOfMemoryError: PermGen

You can increace permgen space with the undocumented JAVA_OPTS="-XX:PermSize=128m -XX:MaxPermSize=256m"

This may be an option for the old PermGen? space problem:

ClassLoader cl = Thread.currentThread().getContextClassLoader();
if (cl == null) cl = getClass().getClassLoader(); // fallback
Class clazz = cl.loadClass(name);
