+ * via the wrong method type.  As with the bytecode representation of
+ * normal Java method calls, method handle calls are strongly typed
+ * to a specific type descriptor associated with a call site.
+ * <p>
+ * This exception may also be thrown when two method handles are
+ * composed, and the system detects that their types cannot be
+ * matched up correctly.  This amounts to an early evaluation
+ * of the type mismatch, at method handle construction time,
+ * instead of when the mismatched method handle is called.
