Hessian error: BasicDeserializer (and Oracle CLOBs?)

Hello,

We're experiencing an odd error related to Hessian on our Java application.

We're running the application on an Orion server, accessing data from an
Oracle database. When we run the application with Orion running on our local
PCs, it all works fine. However, when we try and run it from an Orion server
running upon Solaris, we get the following error:

java.lang.UnsupportedOperationException:
com.caucho.hessian.io.BasicDeserializer@xxx
        at com.caucho.hessian.io.Deserializer.readMap(Deserializer.java:79)
        at
com.caucho.hessian.io.HessianInput.readObject(HessianInput.java:999)
        at
com.caucho.hessian.server.HessianSkeleton.invoke(HessianSkeleton.java:134)

It occurs when data is loaded from the Oracle database. It's difficult to
know for sure, but we think that it's when the application is loading data
from an Oracle CLOB object.

We're not sure how to progress this problem. We've exactly duplicated the
config of the local PC Orion installation upon the Solaris server. The Java
code is the same and both applications are looking at the same database.

Version information:

Hessian jar: hessian-3.0.8.jar
Java: 1.4.2_06
Orion: 2.0.6
Solaris: 9
Oracle: 8.1.7.4

Thanks for any assistance,

Mark
