Launch errors are not being printed to terminal

2012-03-14  Omair Majid  <[email protected]>

    Print exceptions to terminal when running in gui mode too.
    * netx/net/sourceforge/jnlp/AbstractLaunchHandler.java: New file.
    * netx/net/sourceforge/jnlp/DefaultLaunchHandler.java: Extend
    AbstractLaunchHandler.
    (DefaultLaunchHandler): New method.
    (printMessage): Moved to parent class.
    * netx/net/sourceforge/jnlp/GuiLaunchHandler.java: Extend
    AbstractLaunchHandler.
    (GuiLauchHandler): New method.
    (launchError): Print the error too.
    (launchWarning,validationError): Call parent's printMessage.
    * netx/net/sourceforge/jnlp/LaunchException.java: Use standard java
    exception chaining. This removes compatibility with pre-java 1.3 class
    libraries.
    (LaunchException(JNLPFile,Exception,String,String,String,String)): Pass
    cause to parent so exceptions are chanined properly.
    (LaunchException(String,Throwable),LaunchException(Throwable)): Call
    parent's constructor.
    (printStackTrace(PrintStream),printStackTrace(PrintWriter),getCause):
    Removed. Use parent's implementation instead.
    (getCauses): Removed.
    * netx/net/sourceforge/jnlp/LaunchHandler.java
    (validationError): Rename argument to clarify meaing.
    * netx/net/sourceforge/jnlp/runtime/JNLPRuntime.java
    (initialize): Redirect output of all handlers to System.err.
    * plugin/icedteanp/java/sun/applet/PluginAppletSecurityContext.java
    (PluginAppletSecurityContext): Likewise.
    * tests/netx/unit/net/sourceforge/jnlp/DefaultLaunchHandlerTest.java,
    * tests/netx/unit/net/sourceforge/jnlp/LaunchExceptionTest.java: New
    file. Contains tests.
