[jira] [Commented] (ARIES-1090) ABBA deadlock in BP container between BlueprintContainerImpl and ReferenceRecipe

["Paul Slater (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARIES-1090?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13710157#comment-13710157 ] 

Paul Slater commented on ARIES-1090:
------------------------------------

locking ServiceRecipe object in BlueprintContainerImpl.notifySatisfaction() appears to only assure serialization of the ensuing processing rather than needing some sort of exclusion with the synchronization in ServiceRecipe.  Therefore it should be ok to change the lock used in ServiceRecipe.
