Invalid parameters passed in ClientJVMSelectionParameters.extract(Map) causes silent applet start failure.

Say we have the following unittest:
====================================
    public void testExtractWithMalformedHeapsizeValues() {
         Map<String,String> parameters = new HashMap<String,String>();
         final ClientJVMSelectionParameters defaultInstance =
                 ClientJVMSelectionParameters.getDefault();

         parameters.put(ParameterNames.SEPARATE_JVM, "true");
         parameters.put(ParameterNames.REQUIRED_JVM_HEAP, "k1000");
         parameters.put(ParameterNames.FX_VERSION, "2.2+");
         ClientJVMSelectionParameters extractedInstance =
                 ClientJVMSelectionParameters.extract(parameters);
         assertTrue("SEPARATE_JVM should have been set",
                 extractedInstance.isSeparateJVM());
         assertEquals("availableHeapSize should have default value",
                 defaultInstance.getAvailableHeapSize(), extractedInstance.getAvailableHeapSize());
         assertEquals("jfx requirement should have been set",
                 new VersionID("2.2+"), extractedInstance.getJfxRequirement());
    }
====================================
The tset result will be:
====================================
Testcase: testExtractWithMalformedHeapsizeValues(sun.plugin2.main.server.ClientJVMSelectionParametersTest): Caused an ERROR
Too many characters after heap size specifier
java.lang.IllegalArgumentException: Too many characters after heap size specifier
        at com.sun.deploy.util.JVMParameters.parseMemorySpec(Unknown Source)
        at sun.plugin2.main.server.ClientJVMSelectionParameters.extract(Unknown Source)
        at sun.plugin2.main.server.ClientJVMSelectionParametersTest.testExtractWithMalformedHeapsizeValues(ClientJVMSelectionParametersTest.java:128)
        at sun.tests.junit.DeployTestCase.runBare(Unknown Source)
====================================

which means that this causes error in server JVM and the client has no knowledge with it. Hence the silent applet start failure.
