Resource Lock including a Finish Instruction blocks orders

Current Situation

• Assume a workflow (see attached copy) that includes
  • a Lock Instruction
  • a Job Instruction followed by a Finish Instruction
• The first order passes the workflow and leaves the workflow with the Finish Instruction
• Any orders subsequently added to the workflow are waiting with the Lock Instruction, though no other order exists in the workflow at the same point in time. 
  • Users have to remove existing orders from the workflow and revoke the workflow and the resource lock.

Desired Behavior

• A Finish Instruction inside a Lock Instruction should release the lock and should allow subsequent orders to acquire the lock.
