Error when building nokogiri with java 1.7.0_60

Opening at the request of @jvshahid as per comment in #1114 :

I get the following error when trying to build the gem:

1. ERROR in ext/java/nokogiri/HtmlSaxPushParser.java (at line 181)

Just tried this on a centos5.11 docker container and it worked:

@ianderse Can you help us reproduce what you're seeing? If not, I'll close in a few days.

@flavorjones I'm willing to bet it's some crazy configuration stuff on our servers, which sadly I do not have control of. Unless someone else sees it, I'd say go ahead and close it.

[jvshahid]

Closing.
