RFR: JDK-8237214: fix for JDK-8236597 reintroduced wrong subexpression

[Vicente Romero]

Hi,

Please review this patch that fixes [1] at [2]. The fix for JDK-8237214 
that I pushed this morning reintroduced a subexpression at JavacParser 
that has been removed by another patch. Both patches were based on the 
same code and both were modifying the same line, then I resurrected a 
condition that was removed by a previous patch.

Thanks,
Vicente
