----------------------------------------

             Summary: NPE on parfor initialization w/o log4j configuration
                 Key: SYSTEMML-1839
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1839
             Project: SystemML
          Issue Type: Bug
            Reporter: Matthias Boehm


When calling SystemML in embedded deployments (e.g., through JMLC), there is not necessarily
a log4j configuration in the classpath or JVM arguments. In such environments the static initialization
of {{ParForStatementBlock}} fails with a nullpointer exception because we try to obtain the
default log level and convert it to string although this default might be null.
