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

[Saverio Trioni (JIRA)]

    [ https://jira.jboss.org/jira/browse/SECURITY-341?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12449407#action_12449407 ] 

Saverio Trioni commented on SECURITY-341:
-----------------------------------------

It's an interoperability issue. If the generated UIDs are different from the older version (and backwards API compatibility is wanted) then a generated one is as bas as a default 1L UID.

> 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:
> eclipse.buildId=M20080911-1700
> java.version=1.5.0_16
> java.vendor=Sun Microsystems Inc.
> BootLoader constants: OS=linux, ARCH=x86, WS=gtk, NL=es_ES
> Command-line arguments:  -os linux -ws gtk -arch x86
> Error
