Nailgun client code has been upgraded to 0.9.1 (1331d14). We need a new ng.exe before the 1.7.3 release.
We shipped 1.7.3 without this.
@enebo Can we see to this for 1.7.5?
How is nailgun compiled on Windows? I should be able to build it...
@enebo make ng.exe which I'd never tried before. https://github.com/jruby/jruby/blob/master/tool/nailgun/Makefile.in#L8
Fixed in commit 2423846
