A DESCRIPTION OF THE PROBLEM :
We found that the PlatformLogger.getLogger(String name) API lacks a null check. It's unreasonable for the parameter name to take a null value, and a null check should be performed, as well as a NullPointerException should be thrown. Additionally, we tested this API using the latest OpenJ9, and OpenJ9 does perform a null check in this case.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
NullPointerException
