[antlr-interest] expecting "class", found 'class'

[Sven Busse]

Hi,

i tried this already with the testLiterals option, but it
doesn't change anything :(
Also, i read, that if you don't set any option, then
testLiterals would be true by default.

The ident rule gobbles up the 'class' key word, think you have to turn
the testLiterals = yes option on the IDENT rule. Just look at the docs
for testLiterals (or an example like the java grammar)
