Summary 0000899: Setting to control formatting of nulls in JSP pages
Description WebLogic has a config setting to make "<%= foo %>" do nothing if foo is null (rather than outputting the string "null"). We have a bunch of legacy JSPs that depend on this behavior. For now I've just hacked AbstractBodyContent to get rid of the code that outputs "null", but it would be nice if this were controlled by a configuration setting.

 Here's the patch for my change -- I am *not* suggesting this be incorporated into the main release, but this may save someone else some time if they look at this bug report wondering how to do the same thing.
