Enum Serialization - not backwards compatible
---------------------------------------------
Key: LANG-317
URL: https://issues.apache.org/jira/browse/LANG-317
Project: Commons Lang
Issue Type: Bug
Affects Versions: 2.2
Environment: JDK 1.5 -> JDK 1.4
Reporter: U. Klinkmüller
Priority: Critical
Fix For: 2.3
In our distributed application we have to deal with different environments. The
server runs in a JDK 1.5 environment while some clients runs with JDK 1.4. In
this scenario we get an error when we try to transfer the result object via
RMI. The error message is:
Exception:BusinessDelegatorComp.login() - connection error ocurred during
loginCORBA MARSHAL 0x4942f89a No; nested exception is:
org.omg.CORBA.MARSHAL: Unable to read value from underlying bridge :
Mismatched serialization UIDs : Source (Rep.
IDRMI:de.fraport.biaf.apm.user.UserRoleEnum:CBEF51ADA936FFFE:D100D6F29BD50386)
= D100D6F29BD50386 whereas Target (Rep. ID

The class causing this problem is derived from
org.apache.commons.lang.enums.ValuedEnum. Aftre some recherches we found on
http://people.apache.org/~bayard/ that there is a upcoming new release 2.3 of
Commons-Lang. We saw that in this release a bug [LANG-286] has been fixed which
seemed to be exactly our problem. We downloaded this version hopening that we
can forget this problem. But unfortunately the problem still exists.
