Module java.compiler

# Package javax.lang.model.util

Utilities to assist in the processing of program elements and types.

Unless otherwise specified in a particular implementation, the collections returned by methods in this package should be expected to be unmodifiable by the caller and unsafe for concurrent access.

Unless otherwise specified, methods in this package will throw a `NullPointerException` if given a `null` argument.
