Bertrand Delacretaz commented on SLING-2617:
--------------------------------------------
Here's what I found - the root cause is that the JasperException class is
correctly available to the scripting.jsp bundle, but not passed anymore
(compared to previous versions of the bundle) to the ClassLoader used to
compile and execute the JSP.
AIUI the failure scenario is:
In JDTCompiler, INameEnvironment.findType uses ctxt.getClassLoader() which is
an org.apache.sling.jcr.classloader.internal.RepositoryClassLoader.
Its parent is a org.apache.sling.commons.classloader.impl.ClassLoaderFacade
with a manager
(org.apache.sling.commons.classloader.impl.DynamicClassLoaderManagerImpl) that
has an org.apache.sling.commons.classloader.impl.BundleProxyClassLoader with
bundle=org.apache.sling.jcr.classloader (as a parent to the
PackageAdminClassLoader)
That BundleProxyClassLoader should instead point to the scripting.jsp bundle.
That RepositoryClassLoader is provided by the JspRuntimeContext, so fixing the
ClassLoader that that returns should fix both the compile and runtime cases.

> Affects Versions: Scripting JSP 2.0.24
> Reporter: Bertrand Delacretaz

> The following script causes a compilation error, "The type
> org.apache.sling.scripting.jsp.jasper.JasperException cannot be resolved" -
> I'll attach the stack trace.
> Without the jsp:setProperty statement the script compiles without error.
> export PORT=8080

> <jsp:useBean id="date" scope="page" class="java.util.Date" />
> <jsp:getProperty name="date" property="time"/>
> <jsp:setProperty name="date" property="time" value="1234"/>
> <jsp:getProperty name="date" property="time"/>
> All good!
