Thank you all for your suggestions. Just to be clear, this error happens for very few users in a sandboxed version of the program that embeds a copy of the JRE. The error happens with JavaAppLauncher and with the launcher provided with javafxpacakager. Nevertheless, I requested to a user who encountered this issue to reset JAVA_HOME and to remove all JVMs he could find in folders "/Library/Internet Plug-Ins", "/Library/Java/JavaVirtualMachines" and "/System/Library/Java/JavaVirtualMachines". From his report, this didn't help at all. :-(
Any other idea of a possible conflict?
