JBPM 4.4 Snapshot: timer expression does not accept EL that return a duration string value

[nsaputro]

HI All,

I have a problem when running timer with EL expression on JBPM 4.4 snapshot. I use an EL expression #{provisioningService.checkStatusDelay} that return a duration string like "2 minutes"

Previously on JBPM 4.3, the EL gets evaluated correctly and timer works as expected but now I get the following error on 4.4 snapshot.

09:15:26,535 ERROR [ExecuteJobCmd:42] exception while executing 'ExecuteActivityMessage[59]'

org.jbpm.api.JbpmException: Invalid basedate type: #{provisioningService.checkStatusDelay} is of type java.lang.String. Only Date and Calendar are supported

Is this a bug or the expected behavior?

Thank you.
