Re: [m2e-users] please help testing m2e 1.5

[Stephen Coy <steve@xxxxxxxxxxxxx>]

I've been trying this out for the last couple of days on the JBossAS/WildFly code base without any problems so far with about 150 projects.

And I'm running comfortably in 1.5G instead of 2.5G.

Idle heapspace is less than 500M rather than the ~1.8G I was seeing before.

Thanks,

Steve Coy
