This refrest fails on MacOS 10.10 debug build on try server.
* This failure can not be reproduced on local MacOS 10.10. (as far as I tried)
* Removing all '東京特許許可局' in the table does not cause the intermittent failure.
* Removing all words whose font is thinner than 500 does not cause the intermittent failure.
* Using only one downloadable(mplus-1p-medium) font does not cause the intermittent failure.
I am going to investigate the failure reason in the future when I get to know more about layout codes.
