Description Eric Kaplan CLA 2003-05-07 10:43:01 EDT 
We have the following issue.  We are using jdk1.4.1_02 on win2000 and notice 
that if we try to serialize an object between two jvms, one running classes 
built outside of eclipse and the other running classes built inside of eclipse, 
we get a class incompatability error serializing from the non-eclipse jvm to 
the eclipse jvm.  While we could set the serial uid to avoid this error, to us 
it seems like a red flag.  Is anyone aware of such a problem?

The specifics are, we are running ejbs compiled outside of eclipse on jboss.  
The client classes, which are shared, were then recompiled inside of eclipse.  
My understanding was they both used the same java.  The stack trace is 
included.  Any help you could give would be appreciated.

Regards

Eric Kaplan

Comment 1 Olivier Thomann CLA 2003-05-07 10:46:23 EDT 
Eclipse is using its own compiler. Therefore there is no garantee that the
computed serial id will be the same between javac and eclipse compiler. This is
a known problem. The computed serial id can actually be different between javac
versions. JDK1.3.1 can lead to a different serial id than JDK 1.4.1 or 1.2.2.
The only way to solve this issue is to set the serial id.
