Hi!
I'm trying to reproduce this, but has not yet succeed.
I also suspect that the internal browser is what's causing this crash.
Is it possible for you to restore the -Xms and -Xmx settings, add
-Djxbrowser.xulrunner.dir=/Users/ecastilla/Applications/soapUI/.JxBrowser
-Dapple.awt.graphics.UseQuartz=true
-Dswing.crossplatformlaf=apple.laf.AquaLookAndFeell
again and only apply
-Dsoapui.jxbrowser.disable=true
i.e. only disabling the browser.
Does this still work as a workaround?
Also you're getting the error
ERROR [errorlog] com.teamdev.jxbrowser.UnsupportedBrowserTypeException: Mozilla engine doesn't support current environment: Mac OS X, 10.6.8, CPU arch: x86_64, Java Oracle Corporation 1.7.0_15, 64-bit

at com.teamdev.jxbrowser.BrowserFactory.createBrowser(Unknown Source)
in the log, and this is due to SoapUI not being able to render a HTML respons in the HTML tab on OS X, but should not be the cause of the crash.
