+
+ 2005-09-16 Andrew Haley <aph@redhat.com>
+
+ * java/io/ObjectStreamClass.java (findAccessibleMethod): Allow
+ protected readResolve(). Rewrite accessibility check.
+
+ 2005-07-07 Jeroen Frijters <jeroen@frijters.net>
+
+ * java/io/ObjectStreamClass.java
+ (findAccessibleMethod): Added code to make method accessible.
+
+ 2005-07-03 Daniel Bonniot <bonniot@users.sf.net>
+
+ * java/io/ObjectStreamClass.java (inSamePackage): New private method.
+ (findAccessibleMethod): Likewise.
+ (cacheMethods): Lookup readResolve and writeReplace using the new
+ findAccessibleMethod().
