To enable the TagInstanceManager, you need to set the system property first.(the value of property is "false" by default.)
You can set a property "org.apache.jasper.Constants.IGNORE_ANNOTATIONS_FOR_TAGS" with a value "true" to switch to the "TagInstanceManager" model.
The property can be set like this:
	java -Dorg.apache.jasper.Constants.IGNORE_ANNOTATIONS_FOR_TAGS=true
