Description

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.
