Prohibited exception thrown

Last modified: 03 December 2024

Reports throw statements that throw an inappropriate exception. For example an exception can be inappropriate because it is overly generic, such as java.lang.Exception or java.io.IOException.

Example:

void setup(Mode mode) {
    if (mode == null)
        throw new RuntimeException("Problem during setup"); // warning: Prohibited exception 'RuntimeException' thrown
    ...
}
