Matthew Champion created JCLOUDS-1112:
-----------------------------------------
Summary: NPE thrown when lookuking up the ID of a AWS security
group from the name
Key: JCLOUDS-1112
URL: https://issues.apache.org/jira/browse/JCLOUDS-1112
Project: jclouds
Issue Type: Bug
Affects Versions: 1.9.2, 2.0.0
Reporter: Matthew Champion
Priority: Minor
A NullPointerException is thrown if JClouds fails to lookup the security group
ID from the name using the EC2SecurityGroupIdFromName function.
This function appears to be used in two classes
AWSEC2CreateSecurityGroupIfNeeded and AWSEC2SecurityGroupExtension.
AWSEC2CreateSecurityGroupIfNeeded:
In 1.9.x after creating a security group JClouds attempts to lookup the ID from
the name. In 2.0.0 it receives the ID as part of the response to the creation
request but uses EC2SecurityGroupIdFromName a security group with the same name
exists.
AWSEC2SecurityGroupExtension:
Same for 1.9.x and 2.0.0. A security group is created by the LoadingCacge
groupCreator and then the ID is looked up by name
