Paul Krill of InfoWorld published an interesting piece today on the Java tools market, in light of recent consolidations. You might want to give it a read here.
From the article:
The Java tools market is in flux, with the recent acquisitions of CodeGear and BEA Systems altering the landscape, leaving developers with fewer independent tools choices...IBM, Oracle, Genuitec, and CodeGear now account for 95 percent of the commercial tools market in the Java space, Masri (CEO of Genuitec) said. But Oracle and IBM have entire infrastructure stacks, so developers risk vendor lock-in with these choices, he said. "The flexibility of being able to move in and out of one-vendor-provided solutions is becoming less and less possible."
