Hahahahahahahahaha.
Fucking no.
Effectively all of Oracle's "open source" things come from Sun Microsystems, upon which Oracle happily latched onto and sucked dry.
Oracle has what's called the "sidaM Touch". It's like the Midas Touch, but instead of gold, everything Oracle touches turns to shit:
Java -> shit (though maybe slightly less so now).
Solaris -> shit. OpenSolaris -> shit, now dead (thank the Lord for illumos).
OpenOffice -> shit.
GridEngine -> shit. Lustre -> almost became shit and died; would have if it weren't for the Oracle-side devs jumping ship.
NetBeans -> in the process of becoming shit.
MySQL -> shit (though it pretty much already was; somehow, though, Oracle managed to make that worse and prompt the existence of MariaDB); I realize this wasn't Sun's, but it's still an open-source project that Oracle assaulted, robbed, and left to die on the cold streets by the dock where Larry Ellison's (admittedly pretty badass) sailboat is docked.
OpenDS -> dead (though it was mercifully forked into OpenDJ).
Project Wonderland -> now limping around as "Open Wonderland" after Oracle forcibly amputated its leg.
By some miracle, the only things that haven't completely turned to shit or died (or both) yet are Virtualbox and SPARC (though OpenSPARC is effectively dead since Oracle didn't continue it).
