The JVM option is -Djava.security.manager, as already suggested by Julian in CALCITE-6590.

Looking at the code, getSubject() only seems to be called when Kerberos authentication is explicitly configured, which typically means Hadoop-related environments, where this option will be needed anyway by the other libraries.
