Two key class files have been omitted from the Solaris JRE build for
JDK 1.1.6. This is with the latest promoted build "I".

The missing files are missing from rt.jar and are:
sun/io/ObjectInputStreamDelegate.class
sun/io/ObjectOutputStreamDelegate.class

These files are present in the JDK classes.zip but not in the JRE rt.jar

This causes all uses of serialization to fail:

java.lang.NoClassDefFoundError: sun/io/ObjectInputStreamDelegate
        at java.io.ObjectInputStream.<init>(ObjectInputStream.java)
        at sun.security.provider.IdentityDatabase.fromStream(IdentityDatabase.java:89)
        at sun.security.provider.IdentityDatabase.fromFile(IdentityDatabase.java:130)
        at sun.security.provider.IdentityDatabase.initializeSystem(IdentityDatabase.java:336)
        at
        at java.security.IdentityScope.initializeSystemScope(IdentityScope.java:73)

KGH 2/25/98

P.S. We have the same problem on win32. The files are in classes.zip
but not in rt.jar
