Programmatic detection of the presence or absence of a SecurityManager at runtime is straightforward. Static analysis can address the presence or absence of code that would attempt to install a SecurityManager if the code were executed. Checking whether the SecurityManager is installed early enough, whether it specifies the desired properties, or whether it is guaranteed to be installed may be possible in some special cases but is not feasible in full generality.
