Ok, So I've been able to inspect the classloaders and I think I see what's
going wrong (though I'm not sure how best to fix it).

Given my two webapps, AppA and AppB running simulatenously in tomcat. I do
the following:

 1. Load AppA
     a. Load normal jsp page (breakpoint not caught -> still using tomcat
default JspFactory)
     b. Load an embeddedJSP page
          i.  Breakpoint caught at static initializer in JSPRuntimeContext
(line 96)   {calling JspFactory.setDefaultFactory(factory); to initialize
JspFactory implementation}
               - JSPFactory classloader is StandardClassLoader (good)
               - JspFactoryImpl classloader is AppA WebAppClassloader (good)
          ii. Breakpoint caught at JSPApplicationContextImpl (line 79)
{calling impl = new JspApplicationContextImpl() to initialize new servlet
context}
              - JspFactoryImpl classloader is AppA WebAppClassloader (good)
              - JSPApplicationContextImpl classloader is AppA
WebAppClassloader (good)

2. Load AppB
     a. Load normal jsp page
             i. Breakpoint caught at JSPApplicationContextImpl (line 79)
{calling impl = new JspApplicationContextImpl() to initialize new servlet
context}. This means that is is still using the JspFactoryImpl set in step
1.b.i above
              - JspFactoryImpl classloader is AppA WebAppClassloader
(bad!!!  using class loaded in AppA classloader)   !!!!!
              - JSPApplicationContextImpl classloader is AppA
WebAppClassloader (bad!!!  using class loaded in AppA classloader)   !!!!!
     b. Load embedded jsp page
             JSPApplicationContextImpl (line 76) tries to call {
JspApplicationContextImpl impl = (JspApplicationContextImpl)
context.getAttribute(KEY); }   and throws ClassCastException because impl
class returned by context.getAttribute(KEY) was loaded by
AppAWebAppClassLoader but current class (JspApplicationContextImpl) class
loader is now AppB WebAppClassLoader.

It is as I suspected in my last email. I don't think that the JspFactoryImpl
class set by JspFactory.setDefaultFactory(factory) when AppA was loaded
should be the one used by AppB. Somehow the JspFactoryImpl used should
probably be isolated by web application and if possible should only be used
by the embeddedJSP compiler (not used globally for normal jsps as well)
