A good outcome of this J1 should be: no more owls for NetBeans IDE
I was preparing a short post about that, but I've run into an InfoWorld comparison of the fourth major IDEs, so I can just quote it (emphasis is mine):
When Oracle acquired Sun earlier this year, there was considerable concern in the Java community regarding the fate of NetBeans. ... NetBeans' fate appeared so uncertain, we postponed this roundup until we could get a definitive word about the IDE's future from Oracle.
Oracle's decision to continue supporting NetBeans was communicated to us by Duncan Mills, the company's head of product management for developer tools. Said Mills, "We actively support both JDeveloper and NetBeans. JDeveloper is used internally and by our enterprise customers, who need a tool that robustly supports the Oracle Fusion Middleware solutions. NetBeans is our IDE offering for users who want an environment to develop with other technologies. We hope that they will eventually want to migrate to Oracle solutions and JDeveloper." With this pronouncement, it is safe to expect that NetBeans will continue its active pace of development.
Also, worth while mentioning this survey (emphasis is mine):
NetBeans has made large strides in market share (measured by rate of adoption) during the last five years. According to an annual survey of Java IDEs published by New York-based BZ Research, NetBeans was in use at 17.9 percent of respondents' sites in 2005. As of this year, that number had doubled to 35.7 percent. This is by far the largest increase in adoption of any Java IDE during this period. In terms of popularity, NetBeans is now safely ensconced in the No. 2 spot behind Eclipse.
Note that in the final scorecard, NetBeans IDE placed 2nd behind IDEA and just a hair above Eclipse. InfoWorld judged NetBeans greatly easier to use than Eclipse; where we have to recover ground is in the plugin ecosystem. I should also note that in the survey there was no mention about Maven integration, which is another strong point of NetBeans (and IDEA) over the other two IDEs.
