Public bug reported:
The Desktop.browse functionality of Java is not supported on the Kubuntu
16.04 level of the KDE desktop. It was supported in earlier levels.
With this support no longer available, a Java application can no longer
activate the system's browser to display the already-installed HTML help
files for the application, making the context-sensitive help
functionality useless.
Here is the Java code snippet where the code attempts to activate the
online help:
if (Desktop.isDesktopSupported())
{
Desktop desktop = Desktop.getDesktop() ;
if (desktop.isSupported(Desktop.Action.BROWSE))
{
try
{
desktop.browse(new URI(url)) ;
}
catch (Exception e)
{
String error = "Problem creating URI to access
documentation:\n" + e.getMessage() ;
reportError(error, true) ;
}
}
else
reportError("Desktop.browse not supported on this system.",
true) ;
}
When this code is executed, the "Desktop.browse not supported on this
system." error message is displayed, rather than activating the user's
Internet browser to display the HTML help file already installed in the
user's file-system.
In prior releases of Kubuntu, this has always worked. I expected it to
work on 16.04 (as it does on the other 'flavors' of Ubuntu 16.04), but
it is not supported in the KDE desktop of Kubuntu 16.04
I am using Kubuntu 16.04.
In prior releases of Kubuntu, the online help information was displayed
using the system's Internet browser, which was what I expected to
happen.
In this release, I instead got the "Desktop.browse not supported on this
system." error message, and the Internet browser was not activated to
display the already-installed (via Debian package) help information.
