      Steps to Reproduce

        • For example: test.topic

      Expected Results

      Actual Results

      1. An error occurs: 
        An unknown server error has occurred.

      An error in atlassian-confluence.log occurs:

      java.lang.IllegalArgumentException: Invalid label 'test.topic'
	at com.atlassian.confluence.labels.DefaultLabelManager.validateLabel(DefaultLabelManager.java:672)
	at com.atlassian.confluence.labels.DefaultLabelManager.createLabel(DefaultLabelManager.java:645)
	at com.atlassian.confluence.labels.CachingLabelManager.createLabel(CachingLabelManager.java:386)

	at com.atlassian.confluence.plugins.questions.contenttype.repository.QuestionsLabelManager.createLabel(QuestionsLabelManager.java:24)
	at com.atlassian.confluence.plugins.questions.contenttype.repository.LabelTopicRepository.create(LabelTopicRepository.java:132)
	at com.atlassian.confluence.plugins.questions.contenttype.repository.LabelTopicRepository.create(LabelTopicRepository.java:126)
	at com.atlassian.confluence.plugins.questions.service.TopicServiceImpl.createTopic(TopicServiceImpl.java:132)
...

      Root Cause

      A Topic follows the validation for a label in which these characters are not permitted:

      LabelParser.java
          private static final SortedSet<Character> INVALID_LABEL_CHARACTERS = ImmutableSortedSet.of(
            ':', ';', ',', '.', ' ', '?', '&', '[', ']', '(', ')', '#', '^', '*', '@', '!', '<', '>'
    );

      The label validation error is shown when creating a "Label":

      It appears the above informative exception when creating a label is not propagated to Confluence Questions add-on when creating a Topic.

      Resolution

      Change the Topic name so it does not contain one of the above mentioned special characters.
