Trying to morph a bean A into another bean B where B has a property that does NOT exist in A causes a NPE.

The corresponding "offending" code are the following lines:
100 PropertyDescriptor sourcePd = PropertyUtils.getPropertyDescriptor( sourceBean, name );
101 if( sourcePd.getReadMethod() == null ){

As can be seen, when the property with the corresponding name does not exist, getPropertyDescriptor returns 'null' and the expression in the if will cause the NPE.

The corresponding fix should be:

if( sourcePd != null){
if( sourcePd.getReadMethod() == null ){
log.warn( "Property '" + sourceBean.getClass()
.getName() + "." + name + "' has no read method. SKIPPED." );
continue;
}
sourceType = sourcePd.getPropertyType();
}else{
log.warn( "Property '" + sourceBean.getClass()
.getName() + "." + name + "' does not exist. SKIPPED." );
continue;
}
