Android Java Docset

[restaurant review]

Hi guys, 

I used ZEAL before and I don't think this happened before. Today, I installed it again to test for my competition that is coming in 2 days and tried browsing the Android docset's guides. When clicking on Java, it does nothing and does not switch from Kotlin to Java.

This was reported a year ago, and supposedly it was because of some javascript issues presented when seen in the browser. 

Any idea how to fix because it's very important for me.
