Description
Since JDK7b143 the following code throws GenericSignatureFormatError:
---------------------------------------------------------------------------
Class c = Class.forName("javax.swing.JComboBox$AccessibleJComboBox");
System.out.println("Class = " + c);
for ( Field f : c.getDeclaredFields()) {
System.out.println(" [FIELD] " + f.getName());
System.out.println(" [TYPE] " + f.getType());
System.out.println(" [GENERICTYPE] " + f.getGenericType());
}
---------------------------------------------------------------------------
The output is:
---------------------------------------------------------------------------
Class = class javax.swing.JComboBox$AccessibleJComboBox
[FIELD] popupList
[TYPE] class javax.swing.JList
[GENERICTYPE] class javax.swing.JList
[FIELD] previousSelectedAccessible
[TYPE] interface javax.accessibility.Accessible
[GENERICTYPE] interface javax.accessibility.Accessible
[FIELD] editorAccessibleContext
[TYPE] class javax.swing.JComboBox$AccessibleJComboBox$EditorAccessibleContext

in JDK7b140, for instance, the code prints:

Class = class javax.swing.JComboBox$AccessibleJComboBox
[FIELD] popupList
[TYPE] class javax.swing.JList
[GENERICTYPE] class javax.swing.JList
[FIELD] previousSelectedAccessible
[TYPE] interface javax.accessibility.Accessible
[GENERICTYPE] interface javax.accessibility.Accessible
[FIELD] editorAccessibleContext
[TYPE] class javax.swing.JComboBox$AccessibleJComboBox$EditorAccessibleContext
[GENERICTYPE] class javax.swing.JComboBox$AccessibleJComboBox$EditorAccessibleContext
[FIELD] this$0
[TYPE] class javax.swing.JComboBox
[GENERICTYPE] class javax.swing.JComboBox
