I not sure, whether our problem is related to this one, but I’d like to give you the information in case it might be useful. The problem occurred to us for the first time after upgrading our JRE from 1.7.0_09 to 1.7.0_11. In our application, we have a bean class that derives another bean class, and the latter provides an indexed property. If the first access to that indexed property (after starting the JVM) is made via the derived class, everything is fine (see test case DerivedFirstTest). But if we access that indexed property for the first time via the base class, it’s impossible to set the property in the derived class (see BaseFirstTest). It seems that a call to PropertyUtilsBean.getPropertyDescriptors() on the base class “ruins” the property descriptors for the derived class (see IntrospectionTest). May be the work-around for bug 28358 modifies the descriptors received form java.beans.BeanInfo in a way, that is not compatible with the caching of the property descriptors inside the JRE classes. Wouldn’t it be safer to work on a copy of the property descriptor when modifying it?

Hi Maxim,
your patch will cause failures in the test environment (see below). I still
don't understand what exactly is causing the failures in your application. It
would helpful to have some example code that reproduces the failure.
TIA!
