OldJIDLObjectKeyTemplate

public final class OldJIDLObjectKeyTemplate extends OldObjectKeyTemplateBase
Handles object keys created by JDK ORBs from before JDK 1.4.0.

Fields Summary
public static final byte
NULL_PATCH_VERSION
JDK 1.3.1 FCS did not include a version byte at the end of its object keys. JDK 1.3.1_01 included the byte with the value 1. Anything below 1 is considered an invalid value.

         * JDK 1.3.1_01 had the value 1.  If other patches are necessary
         * which involve ORB versioning changes, they should increment
