Review request for JDK-8064571: java/lang/instrument/IsModifiableClassAgent.java: assert(length > 0) failed: should only be called if table is present

[Eric McCorkle]

Hello,

Please review this simple fix for a JDK test failure that was introduced
by the change for JDK-8058313.  A condition for an assertion was left as
">", when it should have been changed to ">=".

Note that this only occurs in artificial test cases; javac does not
produce classfiles with zero-length MethodParameters attributes.
