Start Timer - Cron Expression Error

[mjacobi]

I had some problems using a start timer with the following cron expression:

0 0 9 L-1 * ?‍

According to the documentation http://quartz-scheduler.org/documentation/quartz-2.x/tutorials/tutorial-lesson-06 this expression should work without a problem. Activiti somehow mis-interpreted this expression. The result was that the engine continously created new process instances (about 3-4 per second).

My mistake or activiti's?

In the user guide we refer to Quartz 1 for the support. Is it supported there as well?
The class org.activiti.engine.impl.calendar.CronExpression contains all the parsing code at contains a lot of JavaDoc to show what's supported.

Best regards,

Seems that the expression I used is not supported in Quartz 1. The expression "L-##" is not mentioned.
