[jboss-jira] [JBoss JIRA] Commented: (SECURITY-341) Default serialVersionUID (=1L) in class org.jboss.security.SimplePrincipal prevents interoperability with external tools (e.g. JBossTools)

[Stefan Guilhen (JIRA)]

    [ https://jira.jboss.org/jira/browse/SECURITY-341?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12449426#action_12449426 ] 

Stefan Guilhen commented on SECURITY-341:
-----------------------------------------

I agree that we should remove the serial version UID from classes that existed prior to AS5 - they introduce incompatibility issues.

Whatever value we choose for the new classes, we must keep in mind that we must pay attention to the changes made later on, as they may require us to change the field's value to clearly indicate that the new version of the class won't work with older versions. For this reason I would choose to use the generated ids - if something changes in the class that will make it incompatible with older versions, we just re-generate the id value.

> The serialVersionUID field in class SimplePrincipal is set to 1L instead of the expected 7701951188631723261L. This breaks compatibility with the external tools, preventing interaction with the server.
> Specifically, the application server started from within Eclipse fails early (in about or less than 1 second from starting) with the following exception:
