Issue:
When try to call non-exsitent JS var/method from within Applet via JSObect.eval(...), no exception is thrown.
While JSobejct.getMemeber and JSOjbect.call throw JSException as expected.

source code:
====================
 public void start() {
        testname = "JSobjectgetMemberPropertyTest";
        try {
            win.getMember("nonExistentProerty");
            t.append(testname + " FAILED: Exception should get thrown \n");
            MsgPrinter.printMsg(testname
                    + " FAILED: Exception should get thrown");
            testFlag = false;
        } catch (Exception e) {
            t.append(testname + " PASSED: " + e.toString() + "\n");
            MsgPrinter.printMsg(testname + " PASSED: " + e.toString());
        }
        testname = "JSobjectInvalidEvalTest";
        try {
            win.eval("nonExistentProerty");
            t.append(testname + " FAILED: Exception should get thrown \n");
            MsgPrinter.printMsg(testname
                    + " FAILED: Exception should get thrown");
            testFlag = false;
        } catch (Exception e) {
            t.append(testname + " PASSED: " + e.toString() + "\n");
            MsgPrinter.printMsg(testname + " PASSED: " + e.toString());
        }
        testname = "JSobjectCallInvalidMethodTest";
        try {
            win.call("nomethod", new String[] {});
            t.append(testname + " FAILED: Exception should get thrown \n");
            MsgPrinter.printMsg(testname
