[jboss-jira] [JBoss JIRA] (AS7-3630) Method createTimer(Date date, Serializable info) creates timer which is invoked even the date is in past

    [ https://issues.jboss.org/browse/AS7-3630?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12664647#comment-12664647 ] 

Stuart Douglas commented on AS7-3630:
-------------------------------------

The problem with disallowing this is that you can run into situations like:

- client calculates date a small amount of time in the future
- JVM pauses (e.g. GC pause, heavy machine load)
- By the time createTimer is called date is now in the past, and timer is never invoked.

Not sure how best to avoid this, maybe some kind of threshold.

> In case that I used constructor createTimer(Date date, Serializable info) I set a date which time was in past the timer was created and timeout method was invoked.
