I wanted to write a post about the new Eclipse Helios, which was just released to participate in the Helios Blogathon. So, on my personal machine, I installed the newest JDK (1.6u21), the new eclipse, started it up, tried to work with it and after a few seconds.... It just hangs!
But whait - it worked nicely on my work machine, so what's the deal? Did I install the wrong plug-ins? Tried to open up the wrong editor? I had the same problem on my work machine (Windows 7 x64 with the newest Java 64 bit (1.6u21)). On this machine I fixed it using the 32 bit Java version instead (which just happend to be 1.6u20).
After spending several hours with several 32 and 64 bit versions of Eclipse and Java, I found the deadly combination. It is:
- Windows 7 x64 (may be unrelated to the problem)
- Java 1.6 u 21
- Eclipse Helios
The fix? Get an older Java Version - which is not simple - if you try to get an older version of Java, Oracle asks you to register and wants your email address. They don't tell you that there is a public archive of older Java versions. Why should they? You always want the latest version, right? Even if this means your Eclipse Helios session is limited to 5 seconds.
Helios now runs fine on an Jdk 1.5, with a separate JDK 1.6 installed to actually run my apps.
