Been doing some research since my last post. Here's the setup, same
application code, same struts jars, same app server switching between JDK
1.3.1 and 1.4.1:
When processing a submit, in the PropertyUtils the following check is made
in the getIndexedProperty method on or around line 468:
if (descriptor instanceof IndexedPropertyDescriptor) {
With JDK 1.3.1 running descriptor is indeed an IndexedPropertyDescriptor,
but with JDK 1.4.1 I get a java.beans.PropertyDescriptor, so the code passes
by the block that should handle the property I've passed an onto a block of
code that results in the IndexOutOfBoundsException.
This seems like a 1.4.1 induced bug. Should I log it in Bugzilla? Has
anyone else seen this bug?
