With 7u45, the call from JS to java is failed when applet is using class attribute.

Steps to reproduce:
    1 Install latest jre7u45#224
    2 Enable trace and java console from JCP
    3 Disable OCSP/CRL check from JCP: Open JCP->Advanced->"Perform certificate revocation checks on: ": Check "Do not check (not recommended)"
    4 Load applets that using class attribute to specify applet code:
http://sqeweb.us.oracle.com/net/sqenfs-1/export1/comp/jsn/users/crystal/DO_NOT_REMOVE_ME/jrebug/liveconnect/html/testAccessNonExistentField_Negative.html
    5 There will be an unsigned dialog shows up. Click "Run"
    6 If you don't see " PASSED : Non existent field noJavaField accessible : undefined" shown in java console, this issue is reproduced.

Note:
1) It works fine with 7u40 when use class attribute:
    1 Install latest jre7u40
    2 Enable trace and java console from JCP
    3 Disable OCSP/CRL check from JCP: Open JCP->Advanced->"Perform certificate revocation checks on: ": Check "Do not check (not recommended)"
    4 Load applets that using class attribute to specify applet code:
http://sqeweb.us.oracle.com/net/sqenfs-1/export1/comp/jsn/users/crystal/DO_NOT_REMOVE_ME/jrebug/liveconnect/html/testAccessNonExistentField_Negative.html
    5 There will be an unsigned dialog shows up. Click "Run"
    6 You will see " PASSED : Non existent field noJavaField accessible : undefined" shown in java console

2) Liveconnect call from JS to java is allowed when applet is using jar files instead of class attribute.
steps to reproduce:
1 Install 7u45
2 Enable trace and java console from JCP
3 Load an applet that using unsigned jar instead of class attribute to specify applet code:
http://sqeweb.us.oracle.com/net/sqenfs-1/export1/comp/jsn/users/crystal/DO_NOT_REMOVE_ME/jrebug/liveconnect/html/test_JS2SJ_Unsigned_Sandbox.html
4 In above applet, js -> unsigend java (jar) from same domain
5 A unsigned dialog will show up. Click "Run"
6 You will see ">>>Result is true Cause: method MixedCodeApplet.fromJS get called successfully from JS" shows up in java console(this means that JS to unsigned jar call is allowed)
