It appears that String.isEmpty() is a JDK 1.6 feature. Since we want JDK 5+ compatibility, this is obviously a bug.

Thanks for pointing that out, I'll fix it straight away on trunk.

Hi,

I've found another String.isEmpty() Java 6 reference in the Activiti source (org.activiti.engine.impl.persistence.entity.TaskManager) within the deleteTasksByProcessInstanceId() method and wondered whether it has been fixed since the 5.9 release:

String reason = (deleteReason == null || deleteReason.isEmpty()) ? TaskEntity.DELETE_REASON_DELETED : deleteReason;Is Java 5 support going to continue for the foreseeable future?

Many thanks

Alistair

This is fixed for 5.10, thanks for reporting.
