      I have the following methods:

      def executeCake(String target, String configuration, Boolean failOnError, String... arguments) {
    // Some fancy logic
}
def executeCake(String target, String configuration, String... arguments) {
    executeCake(target, configuration, true, arguments)
}

      Now when running this in Jenkins, it fails to find the correct method and ends in the following exception:

      java.lang.IllegalStateException: cannot compare public java.lang.Object project.Utilities.executeCake(java.lang.String,java.lang.String,java.lang.Boolean,java.lang.String[]) to public java.lang.Object project.Utilities.executeCake(java.lang.String,java.lang.String,java.lang.String[])

      This is probably due to an incomplete implementation of choosing the most specific method:
