Client GUI is unresponsive due to looping subvariable

Issue/Introduction

Applications Manager Client GUI may become unresponsive if a Job contains a looping subvariable. 

A  looping subvariable is when subvar A resolves to subvar B and subvar B resolves to subvar A. 

When RMI process tries to resolves subvar A, this causes the RMI to go into an infinite loop of resolving the subvar. The following can be observed when this occurs:

• GUI becomes unresponsive
• Jobs stop processing
• If debug is enabled, the RMI log will rollover every minute. Additionally the subvar loops will be seen in the log. Below are 2 examples of looping subvars :

 
Example 1:
Line 273721: 12:04:51.62 rfp0: .ResolveSubvars: {#2} -> #1
Line 273722: 12:04:51.62 rfp0: .ResolveSubvars: #1 -> #2
Line 273723: 12:04:51.62 rfp0: .ResolveSubvars: #2 -> #1
Line 273724: 12:04:51.62 rfp0: .ResolveSubvars: #1 -> #2

Example 2:
09:27:51.683 Conditions_AfterOrDelete0: .ResolveSubvars:  resolving variable:condition1 of {condition1}* for jobid:943833
09:27:51.683 Conditions_AfterOrDelete0: .ResolveSubvars: Resolves to: *{condition1}*
09:27:51.683 Conditions_AfterOrDelete0: .ResolveSubvars:  resolving variable:condition1 of {condition1}* for jobid:943833
09:27:51.683 Conditions_AfterOrDelete0: .ResolveSubvars: Resolves to: *{condition1}*
09:27:51.683 Conditions_AfterOrDelete0: .ResolveSubvars:  resolving variable:condition1 of {condition1}* for jobid:943833
09:27:51.683 Conditions_AfterOrDelete0: .ResolveSubvars: Resolves to: *{condition1}*
09:27:51.683 Conditions_AfterOrDelete0: .ResolveSubvars:  resolving variable:condition1 of {condition1}* for jobid:943833
09:27:51.683 Conditions_AfterOrDelete0: .ResolveSubvars: Resolves to: *{condition1}*
09:27:51.683 Conditions_AfterOrDelete0: .ResolveSubvars:  resolving variable:condition1 of {condition1}* for jobid:943833
09:27:51.683 Conditions_AfterOrDelete0: .ResolveSubvars: Resolves to: *{condition1}*
