Hi guys, I seem to be running into the same or a similar problem when trying to run a GAE app in dev mode on MacOS. Have you looked in your system.log (e.g. using Console.app)? I am getting:
Mar 12 12:29:40 Stefans-MacBook java[1407]: [Java CocoaComponent compatibility mode]: Enabled Mar 12 12:29:40 Stefans-MacBook java[1407]: [Java CocoaComponent compatibility mode]: Setting timeout for SWT to 0.100000 Mar 12 12:29:45 Stefans-MacBook mds[35]: (Warning) Server: No stores registered for metascope "kMDQueryScopeComputer" Mar 12 12:29:45 Stefans-MacBook ReportCrash[1409]: Saved crash report for java[1407] version 1.0 (1.0) to /Users/Stefan/Library/Logs/DiagnosticReports/java_2011-03-12-122945_Stefans-MacBook.crash In the crash-report file mentioned above I am seeing the following: Process: java [1362] Path: /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/bin/java Identifier: java Version: 1.0 (1.0) Code Type: X86 (Native) Parent Process: eclipse [1242] Date/Time: 2011-03-12 12:15:57.436 +0100 OS Version: Mac OS X 10.6.6 (10J567) Report Version: 6 Exception Type: EXC_BAD_ACCESS (SIGBUS) Exception Codes: KERN_PROTECTION_FAILURE at 0x0000000000000000 Crashed Thread: 10 Dispatch queue: com.apple.root.low-priority (Followed by a bunch of info about different processes.) I don't really know what to make of this. I have tried launching the GAE devmode using an older JRE-version but this does not help. According to Apple the EXC_BAC_ACCESS / KERN_PROTECTION_FAILURE: "This is caused by the thread trying to write to read-only memory. This is always caused by a data access." [1] I am running Snow Leopard with the most recent Java Update and the most recent GAE SDK. Anybody else got any thoughts in this?
