Enable FastSwap in Weblogic deployment to load java classes at runtime without relaoding the classloader

 Fast Swap
Specifies whether FastSwap deployment is used to minimize redeployment since Java classes are redefined in place without reloading the ClassLoader. For more information, see "Using FastSwap Deployment to Minimize Redeployment" in Deploying Applications to Oracle WebLogic Server.

Refresh Interval
FastSwap checks for changes in application classes when an incoming HTTP request is received. Subsequent HTTP requests arriving within the number of seconds specified here will not trigger a check for changes. The first HTTP request arriving after the number of seconds specified here have passed, will cause FastSwap to perform a class-change check again.

Redefinition Task Limit

The following types of changes are supported with FastSwap:

• Removal of instance methods
• Changes to static method bodies
