Two issues:

1.) Two of the QA ace:audioPlayer tests are failing when using glassfish 4.1 and all browsers. These tests can not be launched due to HTTP Status 500 Internal Sever Error. Not an issue with Tomcat 7.
Test apps located at:
http://dev.icesoft.com/svn/repo/qa/trunk/Regression-Icefaces4/Sparkle/Manual/audioPlayer

> ace:audioPlayer dynamic JSF resource attribute test
exception
javax.servlet.ServletException: Cant instantiate class: org.icefaces.audioPlayer.ResourceBean.
root cause
com.sun.faces.mgbean.ManagedBeanCreationException: Cant instantiate class: org.icefaces.audioPlayer.ResourceBean.
root cause
java.lang.NullPointerException

> ace:audioPlayer dynamic byte array value test
exception
javax.servlet.ServletException: Cant instantiate class: org.icefaces.audioPlayer.ByteArrayBean.
root cause
com.sun.faces.mgbean.ManagedBeanCreationException: Cant instantiate class: org.icefaces.audioPlayer.ByteArrayBean.
root cause
java.lang.NullPointerException


2.) This issue occurs only on Firefox when used with Glassfish 4.1 and is visible in the showcase ace:audioPlayer demo as well as the QA test applications. When loading a page the audioPlayer is rendered for a moment then is removed from view. The demo is not usable unless "Play in new window" is selected.
This occurs in all tests in the QA ace:audioPlayer test suite and is accompanied by broken pipe server warning. Not an issue with Tomcat 7.
