### Question:
JMSMessagePropertySupport { public static void checkIdentifierIsntNullTrueFalse(String identifier) { if ("NULL".equals(identifier) || "TRUE".equals(identifier) || "FALSE".equals(identifier)) { throw new IllegalArgumentException("Identifier not allowed in JMS: '" + identifier + "'"); } }  @SuppressWarnings("unchecked") static T convertPropertyTo(String name, Object value, Class<T> target); static void checkPropertyNameIsValid(String propertyName, boolean validateNames); static void checkIdentifierIsntLogicOperator(String identifier); static void checkIdentifierIsntNullTrueFalse(String identifier); static void checkIdentifierLetterAndDigitRequirements(String identifier); static void checkValidObject(Object value);  }### Answer:
@Test(expected = IllegalArgumentException.class) public void testCheckIdentifierIsntNullTrueFalseFalse() throws JMSException { JMSMessagePropertySupport.checkIdentifierIsntNullTrueFalse("FALSE"); }
@Test(expected = IllegalArgumentException.class) public void testCheckIdentifierIsntNullTrueFalseNull() throws JMSException { JMSMessagePropertySupport.checkIdentifierIsntNullTrueFalse("NULL"); }
@Test(expected = IllegalArgumentException.class) public void testCheckIdentifierIsntNullTrueFalseTrue() throws JMSException { JMSMessagePropertySupport.checkIdentifierIsntNullTrueFalse("TRUE"); }
