Congratulations to Frank on getting this far. I'm sure this will help our pace.
I have installed with "java -jar jython-installer-2.7-b2.jar", on Windows 7, including source and documentation. This went smoothly.
I ran the regression tests. With Java 7 I get 22 failures on Windows, which is up quite a bit from what I have come to expect (about 12) in the development environment. Many are familiar, including the float ones I'm working on at present, and some are cascades (due to non-deletion of files), but some look like they may be problems with building the installer.
In particular some relate to missing idna codecs I believe Jim added. I wonder if the related jars are not getting distributed, or onto the class path?
I'll send the output of "jython -m test.regrtest -e -w" (193K) separately to Frank and anyone who asks.
Should we have failing tests in (even) a beta release? I'd feel happier about inserting skips if I knew there was a "FIXME thermometer" somewhere that would move me to treat the underlying causes.
