7u21 b05 Info.plist issues:
1. Copyright year is 2012
<key>NSHumanReadableCopyright</key>
<string>Java Runtime, Copyright (c) 2012, Oracle and/or its affiliates. All rights reserved.</string>

2. Is there a reason to remove CFBundleGetInfoString?
7u17 has:
  <key>CFBundleGetInfoString</key>
  <string>Java Applet Plug-in, Copyright Oracle Corporation 2013</string>
But these lines were removed in 7u21.
I suppose that due to JDK-8000368 there should be
<key>CFBundleGetInfoString</key>
  <string>Java 7 Update 21, Copyright (c) 2013, Oracle and/or its affiliates</string>
