ERROR: SUM tool fails with error "java.lang.NullPointerException" during VALIDATE-QUEUE and ‘Unexpected end of ZLIB input stream’ in SDM logs.

Resolution

• From the SUM trace and logs you have to identify the package SCA which is showing error , you will find in logs just before error mesage with clause "Loading Archive" 
• Download the support packages(SCA) again from service market place and ensure there is adequate disk space to deploy the files. See note 891895 for details. 
• Re-run the SUM(software update manager) to import and deploy the support package(s) from the point it has stopped
