PROBLEM SUMMARY

USERS AFFECTED:
 All users of IBM WebSphere Application
Server Liberty Profile

PROBLEM DESCRIPTION:
An OSGi web app using jsp and jstl by
default currently needs to explicitly
import the jstl spec packages.

RECOMMENDATION:
None

An OSGi  web application using jsps and jstl needs to explicitly
import the jstl spec packages.  Such an application would have
worked on 8558 and will show jsp compilation errors when a jsp
using jstl is accessed.

PROBLEM CONCLUSION:                                             
Classloading structure for jsp for osgi applications has been   
modified so the default setting of the backwards compatibility  
flag makes the jstl spec packages available to any osgi web     
application.
