JDK-4921754 - java.nio exception classes don't specify serialVersionUID
Description
Tested using jdk7 promoted b130.
When did following, error message is not correctly showing the file path.

bash-3.2$ native2ascii xxx
java.lang.Exception: [Ljava.lang.String;@1e91259 could not be read.

It should say "xxx could not be read." instead.
The fix for this bug adds a new test case. When this
test is used on older bits, the test now fails:
