PI67025: SUDO IMPERSONATION FAILING WITH NULLPOINTEREXCEPTION

APAR status

• Closed as program error.

Error description

• When a plugin command with impersonation fails on an agent (ex.
  create file), the user will get a null pointer exception (NPE)
  if the agent property file does not have a value declared for
  property
  com.urbancode.shell.impersonation.unix.scriptPostExecuteAction.
  
  The NPE masks the actual IO exception that the user would see if
  the NPE was not thrown. This makes it difficult for the user to
  know why the command failed.
  
  A code change is needed to check whether
  scriptPostExecuteAction is null before attempting to execute the
  post-execute action when the plugin command fails.
  

Local fix

• The user can add a valid system command (ex: echo) to the agent
  property file for the property:
  com.urbancode.shell.impersonation.unix.scriptPostExecuteAction.
  
  For example, in the file
  <agent-install-dir>/conf/agent/installed.properties, add the
  property/value pair:
  com.urbancode.shell.impersonation.unix.scriptPostExecuteAction=e
  cho
