I am new to Google App Engine. I am trying to call Amazon's CloudWatch
service using its Java SDKs. I am planning to run this App in Google App
Engine. However at the time of instantiating my AmazonCloudWatchClient in
my code I get the following exception.
access denied (java.lang.RuntimePermission modifyThreadGroup)
Caused by:
