Mixed code scenario where signed jar is calling the unsigned jar is hanging the browser and jnlp application. Same is not true if unsigned jar is calling the signed jar

Steps to reproduce:
1) Install jre an dfxruntime
2) Make sure that mixed code settings are set to default i.e enabled by default
3) Try to load following applet inside the browser
http://sqeweb.us.oracle.com/deployment2/jitu/latest_ws_test/6/deployment/src/javafx/fxfeaturesTest/fxfeaturesTest/html/MixedCodeAppletMainSigned.html
If after security warning, mixed code dialog fails to show up and browser hangs then bug is reproduced

4) Now try to execute mixed code jnlp application as follows
javaws http://sqeweb.us.oracle.com/deployment2/jitu/latest_ws_test/6/deployment/src/javafx/fxfeaturesTest/fxfeaturesTest/html/SimpleMixedCode.jnlp
If after security warning, mixed code dialog fails to show up and jnlp application fails to execute then bug is reproduced
Note: There is already a java-webstart bug related to deadlock if mixed code is executed in multi threading environment, but this scenario there is no multi threading involved at all
