This is a Solaris 9 tracking report for Java report 4378370. Its opened
to track this particular Java 1.3 problem in Solaris 9. FYI, the reason for
this "java_solaris" shadow report is to have the report appear for Solaris 9 bug report data. Solaris 9 bug tracking data doesn't currently include "java"
catagory reports.

This tracking report should stay open until the Java classes fix is integrated
back in to Solaris 9. Its being filed to match the current Priority found in
the report 4378370. See 4378370 for current status. Description from 4378370
is included below.

---------------------
Looks like there is a bug with BigInteger deserialize. Though this has been fixed for Merlin, it still exists in JDK 1.3 and is a regression.
This only occurs when you subclass BigInteger to another class, say UnsignedInt64. When you try to serialize and then deserialize, there is a NullPointerException. If, however, it is merely embedded in a class (and not subclassed), there is no problem. This works fine on 1.2.2_05
I'm attaching two example files. Just run java TestClient to see the result. Our RMI server fails because of this.
Here is a stack trace:
java.lang.NullPointerException
