Potential Problem with ${empty someProcessVariable} or ${someProcessVariable != null}

Description

Potential bug:

org.activiti.engine.impl.el.JuelExpression.getValue, line 48

throws new ActivitiException("Unknown property used in expression", pnfe);

Does this prevent me from writing expressions of the sort:
${empty someProcessVariable} or ${someProcessVariable != null}
