New Revision: 1505199
URL: http://svn.apache.org/r1505199
Log:
Fix for https://issues.apache.org/bugzilla/show_bug.cgi?id=55285
Have JspConfigDescriptor related classes clone collections when returning them
to application code.
As ContextConfig can no longer mutate the config stored in StandardContext,
add a setter to Context to provide a fully configured JspConfigDescriptor
