Description Tomas Hurka 2012-12-01 07:37:51 UTC
It looks like there are several cases, where List.nil() is not used. Example is$JCMethodInvocation.args list. This can save some memory especially in cases, where a lot of sources are parsed.
Comment 1 Tomas Hurka 2012-12-01 09:10:45 UTC
It looks like ListBuffer is creating this empty List instances.
Comment 3 Quality Engineering 2012-12-14 02:42:29 UTC
