Here is an overview of the issue:
        Key: GERONIMO-95
    Summary: [PATCH] DeploymentPlan may not query all tasks in canRun()
       Type: Bug

     Status: Unassigned
   Priority: Minor

 Time Spent: Unknown
  Remaining: Unknown

    Project: Apache Geronimo

   Reporter: Gareth Bryan

In o.a.g.kernel.deployment.DeploymentPlan.canRun(), incorrect usage of the short-circuit AND
operator means that if a previous task reported that it could not run, subsequent tasks will
not be queried.

This is the opposite to the indened behaviour which is documented in the code comment "always
check each task, so the task can throw an exception if the task can never run".

The patch file is a trivial change from:

canRun = canRun && task.canRun()


canRun = task.canRun() && canRun

The patch was generated by running "cvs diff -uN" from the project root directory (incubator-geronimo).

Also included in the patch and attached zip file is the testcase which brought this problem
to light.
