[jboss-jira] [JBoss JIRA] (WFLY-2949) Cannot get exception as pass-by-reference

[David Lloyd (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-2949?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12945600#comment-12945600 ] 

David Lloyd commented on WFLY-2949:
-----------------------------------

The patch looks OK to me.  It is however worth pointing out for posterity that all {{Throwable}}s implement Serializable; the problem here is likely some field within a custom exception subtype that is in turn not serializable, so this is not a common case.

> Despite of {{<in-vm-remote-interface-invocation pass-by-value="false"/>}}, an exception is not thrown by reference, which results in {{java.io.NotSerializableException}} if the exception doesn't implement {{Serializable}}.  This is a blocker of a large migration project from WebLogic because it throws by reference even if that doesn't implement {{Serializable}}.
