Tuomas Kiviaho opened SPR-8491 and commented

java.awt.Component has both

public void setSize(int width, int height)
and
public void setSize(Dimension d)

introspection of classes derived from this base class (using BeanUtils.getPropertyDescriptor) now crashes with following exception

...
Caused by: java.beans.IntrospectionException: type mismatch between indexed and non-indexed methods: size
at java.beans.IndexedPropertyDescriptor.findIndexedPropertyType(IndexedPropertyDescriptor.java:341)
at java.beans.IndexedPropertyDescriptor.setIndexedWriteMethod(IndexedPropertyDescriptor.java:248)

at org.springframework.beans.CachedIntrospectionResults.<init>(CachedIntrospectionResults.java:224)
... 92 more

I guess that this can be omitted by first checking whether or not index method really has to be updated or not (it seems to be already null)
