Flash Builder 4.5 crash on load OS X 10.7

[Chris_Born]

It was working, the app crashed during a build then would not reload. After a short bit of time it returns an error alert with instructions to look at the log file. Looking at the .log file and the console there are several Java errors (see bellow)

This is a clean install of Lion not a 10.6 upgrade. This is my development machine for Xcode and Air projects, it has no extraneous stuff. Installed Java version is: Java SE 6 32-bit & 64-bit 1.6.0_26-b03-383.

What I've tried so far: Removed the Flash Builder folder from documents and let FB rebuild it. Reinstalled Java and FB 4.5.1 two and three times respectively. Verified disk permissions. Rebooted between several of these steps. Created a new Admin user account, reinstalled both again from that account. Still fails. None of these tasks has resolved the issue.

Any ideas?

UPDATE:

So running the FB uninstaller then the installer again gets me back up and running. However every other time FB crashes, and this is becoming rather frequent, the FB will not start up again. The same issue as above. The only fix I can find is to uninstall and reinstall and I have had to do this about every hour right now. This is reproducable with a completly empty workspace (no projects) and then create a new Air project.

Did you bother to check the compatibility before upgrading???  The initial response wasn't very good and Adobe clearly stated their recommendations were NOT to install 10.7 if you were using Flash Builder.  SInce that time, Adobe has some better news with some recommendations here:

http://blogs.adobe.com/flex/2011/07/updated-guidance-on-flash-builder-4-5-compatibility-with-mac-os-x-10-7.html

I absolutly did read the guidance notes and it was based in them that we installed.

Quote:

"Now that we have had an opportunity to undertake further testing with the final release of Mac OS X 10.7, we are pleased to report that there are only minor usability issues when using Flash Builder 4.5.1 on Mac OS X 10.7 and, as such, we will be updating our previous statement to confirm compatibility of these releases"

What I am now experiencing on two different machines is what appears to be outside the scope of these notes and either a new issue that is reproducible, or a Java issue related to 10.7. Not being a Java guy I'm not sure were to begin short of trying Eclipse on its own.

I am able to produce a crash of FB 4.5.1 by just trying to close an MXML file by clicking the close button of the tab, or by closing a project. This is on two seperate machines now.

Does disabling design view help? (Window -> Enable Design Mode)

The log file indicates that class files required for Builder are missing. But I can't understand how that is reproducible. Maybe that is a side effect of the actual error.

Can you post the full contents of your log? (Create a new workspace by doing File -> Switch workspace, get it to crash and post the log here).
