Comment 5 zolta 2011-02-25 10:51:19 UTC 
Exception occours with NB 6.9.1 on java 1.6.0_21-b06

in a method type the following:

EnumMap<?,Object> linemap;
linemap=new EnumMap

//if you go ahead with typing to

linemap=new EnumMap<>

com.sun.tools.javac.comp.Infer$InvalidInstanceException exception occurrs

Interesting that it does not occour  with
=new TreeMap<>

this is not present in latest dev build (on 110225)
Comment 6 Petr Cyhelsky 2012-11-08 11:46:17 UTC 
Last report is from 6.9.1 - doesn't seem to be a problem any more
