Start using Java 7 with IntelliJ IDEA 10.5 EAP

A while ago we announced the IntelliJ IDEA 10.5 update, focusing on Java 7 support. Now we invite you to start using Java 7 with your favorite IDE: IntelliJ IDEA 10.5 EAP build 106.273 is available for download from the EAP page.

We will continue showcasing user visible improvements of the upcoming release in our blog (like documentation view overhaul, lighter refactorings UI, etc.), so stay tuned.

As an x.5 version, IntelliJ IDEA 10.5 will be a free update for IntelliJ IDEA 10.

IntelliJ IDEA 10.5 is also going to be a massive bug fix release. We need your feedback — welcome to our EAP discussion forum and issue tracker.

P.S. Ah yes, the codename for this version is Xena.

    Very nice, thanks for starting with x.5 releases again!

    And let’s hope this is the last “massive bugfix” by releasing less bugs in the future =).

    One thing to check. Idea’s editor panel does not display properly with XRender being used as the swing display mechanism. The rest of the app displays correctly, so perhaps there’s some setting in the Idea code base which is causing some grief.

    Add this option and try running.
    -Dsun.java2d.xrender=True

    Being able to use XRender for remote X11 displays would really help with display performance. I’m using the linux build of 10.5

    In process compilation appears to hang for a “make project” when some code needs to be build and when using the 1.7.0 JDK.

    Works fine when using a 1.6.0_23 JVM.

  4. Denis Tulskiy says:

    Are there any jdk7 optimizations that you recommend to use when running IDEA? Compressed oops, G1, maybe something else?

  5. Denis Tulskiy says:

    Oh, and the new 10.5 EAP hangs on Refreshing VCS history. Do I need to delete my old profile and start from scratch?

  6. Alan Stange says:

    @Denis
    I believe compresses oops are only for the 64bit JVM, which wouldn’t be too useful for an IDE. I have had mixed luck with G1GC and JDK7….numerous crashes while running IDEA….but works just fine with the latest JDK6. I tend to use
    -server
    -XX:+TieredCompilation
    -XX:+UseG1GC
    and in process compilation is a huge win.
