      protected static <T> T getVariableValue(String name, Function<String,T> conversion, Supplier<T> defaultValueFactory, org.slf4j.Logger logger, boolean exceptionWhenFailing) throws IllegalStateException
      Deprecated.
      Generic method for accessing an environmental variable which has the given name and will be transformed into the return type using the given conversion function. The behavior in case of an error is defined by the given default value and Logger objects. If a problem occurs and a Logger is available, the error will be logged using the Logger.error(String) method. If exceptionWhenFailing is set to true an IllegalStateException is thrown. Else, if a defaultValueFactory is available, a default value will be returned. Otherwise null is returned.
      Parameters:
      name - name of the environmental variable which should be accessed
      conversion - the function which is used to convert the String of the variable value into the expected value type. It is assumed that this function will throw an exception if an error occurs.
      defaultValueFactory - A factory method which can be used to generate a default value which will be returned if the variable can not be found or if an error occurs.
      logger - the Logger which will be used to log errors if they occur.
      exceptionWhenFailing - flag indicating whether an exception should be thrown if an error occurs.
      Returns:
      the variable value converted to the expected value or the default value if an error occurred and a default value is available.
      Throws:
      IllegalStateException - if exceptionWhenFailing is set to true and one of the following two errors occurs: 1) the variable is not available or 2) the conversion function throws an exception.
