rhn-support-cpandey had a case where container was hanging in "downloading" state forever. Heapdump revealed not finished downloading of wrap:mvn:com.amazonaws/aws-java-sdk-osgi/1.11.22, but further investigation showed a problem between successful downloading of innner mvn:com.amazonaws/aws-java-sdk-osgi/1.11.22 and applying "wrap:" to already downloaded artifact.

The exception was swallowed and agent was awaiting wrap:mvn:com.amazonaws/aws-java-sdk-osgi/1.11.22 to finish.

I already have a fix for this problem and:

• real exception is visible in container-list / container-info
• agent switches from "downloading" to "error" state
• real exception is printed in logs (in rhn-support-cpandey's case - OutOfMemoryError)
