Notes

1. Seems to be related to Java version
   • After updating Java to version 8, the issue can be viewed but the thumbnail is still not generated
2. Problem does not happen with JIRA 6.3.15 (Java7)
3. Since JIRA 6.4 supports both Java 7 & 8, JIRA shouldn't be affected by this when Java 7 is used

Workaround

1. Manually generate the thumbnail for this image (instructions found here); OR
2. Upgrade your JAVA version to 1.8.0_05 and above
