[4.1.8] JspCompilationContext:
Use _ instead of $ to generate file and class names for jsp servlets.
+[4.1.19] Compiler:
+ Added new "fork" option. This tells Ant to fork the JSP page javac
+ compile so that it is run in a different JVM from the one Tomcat
+ is running in. Please refer to the Jasper-HOWTO for more information.
