zhzhzoo created FLEX-34451:
------------------------------

             Summary: swfdump throws NullPointerException parsing DEFINEFONT3 Tag
                 Key: FLEX-34451
                 URL: https://issues.apache.org/jira/browse/FLEX-34451
             Project: Apache Flex
          Issue Type: Bug
    Affects Versions: Adobe Flex SDK 4.6 (Release)
            Reporter: zhzhzoo
            Priority: Minor


I was dumping a swf file using swfdump when I encountered a NullPointerException. The file
does't conform to the swf format spec but Adobe Flash Player can play it.

{code}
localhost:font zhzhzoo$ java -jar /Applications/Apache\ Flex/SDK/lib/swfdump.jar  ~/Desktop/xxx/page003.swf
