6u10 b09Fixed
The attached test case shows that a conversion from a JSObject to a Java String needs to be added to the new LiveConnect code for compatibility. The test case runs successfully with the old Java Plug-In but raises a JavaScript error in the new Java Plug-In due to the absence of this implicit conversion.

SUGGESTED FIX http://sa.sfbay.sun.com/projects/deployment_data/6u10/6624949.1 testcase: http://web-east.east.sun.com/deployment/www/tests/1.6.0_10/6624949/

EVALUATION Relaxed the type conversion rules in JavaScript-to-Java calls to allow conversion from JSObject to String. The underlying MessagePassingJSObject already had support for conversion to string. Tested in IE and Firefox.
