We tried using regex in jlink for various filters and found that it made jlink > 10x slower. Granted jlink is time critical and jimage is not. I made the assumption that filter expressions would be very basic, most of the time, and tried to be consistent with filters for both tools. I could easily change it to use regex if not a basic pattern.
Note we also chose not to use java.lang.regex in Nashorn for similar reasons (plus the fact it didn’t meet JS spec. .) Might be worth revisiting regex performance. — Jim > On Jun 1, 2016, at 12:24 PM, Alan Bateman <alan.bate...@oracle.com> wrote: > > On 01/06/2016 15:48, Jim Laskey (Oracle) wrote: > >> http://cr.openjdk.java.net/~jlaskey/8156995/webrev/index.html >> https://bugs.openjdk.java.net/browse/JDK-8156995 > Jim - should this allow regex rather than just "*" ? > > -Alan
