  * @build install/SerialDriver.java test/SerialDriver.java extension/ExtendedObjectInputStream.java
  * @summary Enable resolveClass() to accommodate package renaming.
  * This fix enables one to implement a resolveClass method that maps a
- * Serialiazable class within a serialization stream to the same class
+ * Serializable class within a serialization stream to the same class
  * in a different package within the JVM runtime. See run shell script
  * for instructions on how to run this test.
