Hi guys,
  I notice that Tom didn't finish his job for el refactor.  we could see these issues have not finished yet.

 https://jira.jboss.org/jira/browse/JBPM-2686 https://jira.jboss.org/jira/browse/JBPM-2686
 https://jira.jboss.org/jira/browse/JBPM-2653 https://jira.jboss.org/jira/browse/JBPM-2653
 https://jira.jboss.org/jira/browse/JBPM-1209 https://jira.jboss.org/jira/browse/JBPM-1209
 https://jira.jboss.org/jira/browse/JBPM-2777 https://jira.jboss.org/jira/browse/JBPM-2777

  Some of them were stay on Coding in progress for a long time.  And I think we should consider about them.  And find way to finish the job.

  At this moment, Tom has done lots of works for refactor el from jsr-223 to UEL.  I think he want to remove all of reference for ScriptManger from existing classes except ScriptManager.  And he also said that we should deprecate the language attribute from expr, because after refactor job, the expr will always use UEL to evaluate the value from execution or task.

So I think we could go through his work, let components use org.jbpm.pvm.internal.el.Expression to handle the expr.  Here is the which components are using ScriptManager:
 | jBPM-4.3 | jBPM-4.4 |
 |   | org.jbpm.bpmn.flownodes.ScriptTaskActivity.java |
| org.jbpm.jpdl.internal.activity.AssignActivity.java |   |
| org.jbpm.jpdl.internal.activity.DecisionExpressionActivity.java |   |
| org.jbpm.jpdl.internal.activity.JmsActivity.java | org.jbpm.jpdl.internal.activity.JmsActivity.java |
| org.jbpm.jpdl.internal.activity.RulesFact.java |   |
| org.jbpm.jpdl.internal.activity.ScriptActivity.java | org.jbpm.jpdl.internal.activity.ScriptActivity.java |
| org.jbpm.jpdl.internal.activity.ScriptBinding.java | org.jbpm.jpdl.internal.activity.ScriptBinding.java |
| org.jbpm.jpdl.internal.activity.SubProcessActivity.java | org.jbpm.jpdl.internal.activity.SubProcessActivity.java |
| org.jbpm.jpdl.internal.activity.SubProcessInParameterImpl.java |   |
| org.jbpm.jpdl.internal.activity.SubProcessOutParameterImpl.java |   |
|   | org.jbpm.jpdl.internal.activity.TaskActivity.java |
|   | org.jbpm.pvm.internal.cal.Duration.java |
|   | org.jbpm.pvm.internal.el.ScriptExpression.java |
| org.jbpm.pvm.internal.email.impl.MailProducerImpl.java | org.jbpm.pvm.internal.email.impl.MailProducerImpl.java |
| org.jbpm.pvm.internal.job.TimerImpl.java |   |
| org.jbpm.pvm.internal.model.ExecutionImpl.java | org.jbpm.pvm.internal.model.ExecutionImpl.java |
| org.jbpm.pvm.internal.model.ExpressionCondition.java | org.jbpm.pvm.internal.model.ExpressionCondition.java |
| org.jbpm.pvm.internal.model.VariableDefinitionImpl.java |   |
| org.jbpm.pvm.internal.model.VariableOutDefinitionSet.java | org.jbpm.pvm.internal.model.VariableOutDefinitionSet.java |
| org.jbpm.pvm.internal.script.ScriptManager.java | org.jbpm.pvm.internal.script.ScriptManager.java |
| org.jbpm.pvm.internal.wire.binding.ScriptManagerBinding.java | org.jbpm.pvm.internal.wire.binding.ScriptManagerBinding.java |
| org.jbpm.pvm.internal.wire.descriptor.ExpressionDescriptor.java | org.jbpm.pvm.internal.wire.descriptor.ExpressionDescriptor.java |
| org.jbpm.pvm.internal.wire.descriptor.ObjectDescriptor.java |   |
|   |   |

We could see that some of them had been solved by Tom and Joram.  But there are still some components were not solved yet.  So I want to continue their jobs.  Anyone has any ideas?  Any reply is apprieciate.  Thank you very much.
