[jboss-jira] [JBoss JIRA] Closed: (JBAS-2144) Scheduled task interval calculated from stop to start instead of start to start

Dimitris Andreadis closed JBAS-2144.
------------------------------------

    Fix Version/s: JBossAS-5.0.0.Beta
                   JBossAS-4.0.5.CR1
       Resolution: Done
         Assignee: Dimitris Andreadis

This is solved now. The behaviour is the same in both jdk1.4 and jdk5, which is fixed-delay by default, unless you override this by setting FixedRate to true (as shown in the configuration files).

> When running jboss 4.0.2 final with jdk 1.5.0_04 the calculation of the next start of a scheduled operation becomes (time at END of scheduled operation + interval) instead of (time at START of scheduled operation + interval). This causes scheduled operations to shift in time based on the duration of the scheduled operation. This does NOT happen using jdk 1.4 which might hint at the built-in jmx (and timer instance) in the jvm of 1.5 causing the problem?
