Subject [jira] Commented: (AVRO-12) Bug in comparison of recurisive schemas
Date Tue, 14 Apr 2009 04:37:14 GMT

    [ https://issues.apache.org/jira/browse/AVRO-12?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12698648#action_12698648
] 

Hong Tang commented on AVRO-12:
-------------------------------

Here is the unit test that can reproduce the error (add the code in TestSchema.java):

{code}
  public void testRecursive2() throws Exception {
    String jsonSchema =
        "{\"type\": \"record\", \"name\": \"Node\", \"fields\": {"
            + "\"label\": \"string\","
            + "\"children\": {\"type\": \"array\", \"items\": \"Node\" }}}";
    Schema s1 = Schema.parse(jsonSchema);
    Schema s2 = Schema.parse(jsonSchema);
    assertEquals(s1, s2);
  }
{code}
