Hello,
I'm using JBoss 7.1.1.Final and I ran into the same trouble, I got a @Singleton @Startup annotated class with a @Schedule annotated method. This class was once deployed without persistence=false attribute and now I got old scheduled task being executed. I removed the @schedule class's jar file from JBOSS_HOME/standalone/deployment I delete JBOSS_HOME/standalone/data and JBOSS_HOME/standalone/tmp but I can't get rid off about previous timers, as I redeploy the jar old tasks are executed. Any ideas?
TIA
