Flex Builder 3 on the OSX

January 7th, 2009

After days of watching Flex Builder 3 crash as soon as I opened it, I figured out how to fix it. It seems that Flex Builder doesn’t like the 64 bit version of Java 1.6 that OSX now uses. I had thought this might be an issue so I used the Java Prefences pane to move Java 1.5 up as my default. It didn’t change a thing. I downloaded eclipse to see if it was a Flex Builder issue or an Eclipse issue. Turns out it’s and Eclipse issue.

The solution: You need to specify the exact JVM in the Info.plist file. You can find this file Flex Builder.app -> Contents -> Info.plist

Open that up in your favorite text editor and add a line like so:

 <key>Eclipse</key>
  <array>
      <string>-startup</string>
       <string>../../../startup.jar</string>
      <string>-vm</string><string>/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Commands/java</string>
