After I upgraded to the new version, I noticed the code has "changed".
Well ... the actually code didn't change but what was previously:
item.charAt(0)
was replaced with:
item[0]
as well as other some other changes.
If I hover over item[0], a tooltip pops up showing the real value.
It is slick and a nice surprise (!) and I have no idea what it is called or how to cause it to fine tune it.
This behavior is caused by the Advanced Java Folding plug-in. Either disable the plug-in or change its setting to not fold certain code elements.
