Description

The issue was detected with SwingBuilder where
splitPane(orientation:JSplitPane.VERTICAL_SPLIT)

produced

java.lang.reflect.InvocationTargetException
...
at org.codehaus.groovy.tools.GroovyStarter.main(GroovyStarter.java:160)
Caused by: java.lang.IllegalAccessException: Class
groovy.lang.MetaFieldProperty$2 can not access a member of class java
x.swing.JSplitPane with modifiers "protected"
at sun.reflect.Reflection.ensureMemberAccess(Reflection.java:57)
....

metaClass.setProperty(jSplitPane, 'orientation', 0)
accesses the field instead of the setter method.
(via MetaFieldProperty.setProperty(...))

it's probably an issue with how the metaclass propertyMap was built in the first place.
