Felix Meschberger commented on SLING-1414:
------------------------------------------
Hmm, I found the problem and I think it is really a bug in the Tomcat/Jasper
implementation of the BeanELResolver.getMethod(Class, Method) method. This
method contains a shortcut of the form:
if (m == null || Modifier.isPublic(type.getModifiers())) {
return m;
}
Assuming that the method is declared in the type and if the type is public, the
method may be called.
In our situation, the type is actually "JcrNodeResource" which in fact is
public. But the method (m) is declared by the package private "JcrItemResource"
class. So the short-cut should probably rather be:
if (m == null || (Modifier.isPublic(type.getModifiers()) &&
m.getDeclaringClass() == type)) {
return m;
}
Not 100% sure though. On the other hand we can work around this problem here by
making both JcrNodeResource and JcrItemResource (and also JcrPropertyResource)
either public or package private.
I like package private more, because it is an internal detail of the
JcrResourceProvider implementation also located in the same package.

> Key: SLING-1414
> URL: https://issues.apache.org/jira/browse/SLING-1414
> Project: Sling
> Issue Type: Bug
> Components: JCR
> Affects Versions: JCR Resource 2.0.6
> Environment: CQ5.2.1/CQ5.3
> Reporter: zhangchunlong
> Assignee: Felix Meschberger
> Priority: Minor
>
> Often in the JSPs, we call the ResourceResolver.findResources(query, "xpath")
> method to return an Iterator<Resource> object, which we iterate through using
> JSTL and EL syntax. When we attempt to access the getPath() method of each
> Resource, the following exception is thrown:
> java.lang.IllegalAccessException: Class javax.el.BeanELResolver can not
> access a member of class
> org.apache.sling.jcr.resource.internal.helper.jcr.JcrItemResource with
> modifiers "public".
> This works with CQ5.2.1 with no problem before. The issue happens on CQ5.3 GA
> release.
> Example codes to re-produce the error in CQ5.3.
> Iterator<Resource> found = resourceResolver.findResources("//element(*,
> nt:unstructured)","xpath");
> while(found.hasNext()){
> try{
> Resource foundResource = found.next();
> pageContext.setAttribute("foundResource", foundResource);
> %>${foundResource.path}<%
> }
> catch(Exception e){
> %><%=e.getMessage()%><%
