Comment 6 for bug 1171506

On firefox i386, if I go to the bank url, it takes a few seconds to load, and then I get a 'Security Approval Required' dialog. If I click 'Run' (and uncheck 'Always trust content from this publisher'), then it starts to load and after a few seconds a second 'Security Approval Required' dialog is presented. If I click 'Run' again (and uncheck 'Always trust content from this publisher'), I see what appears to be a login screen. Note, I had to use https://www2.bancobrasil.com.br/aapf/login.jsp because the one specified seemed to be associated with your account (it told me it could not recognize the computer). This is with the icedtea6-plugin (6b21.2.3-0ubuntu0.12.04.1).

If I install the icedtea-7-plugin, it says: 'Start:applet not initialized' if I go to the original bank URL. If I launch this from a terminal, I see:

This seems to be the problem:
Unable to find class net.sourceforge.jnlp.security.VariableX509TrustManagerJDK7

The debian/changelog has:
 * Common:
    - PR1161: X509VariableTrustManager does not work correctly with OpenJDK7

This is http://icedtea.classpath.org/hg/release/icedtea-web-1.2/raw-rev/c74251bbaffd. I'll try reverting it and report back. The workaround appears to be to use icedtea6-plugin on 12.04 for now.
