Hi Xavier,
The class org/eclipse/jdt/internal/launching/JavaLocalApplicationLaunchConfigurationDelegate is not available in 3.1M6, however it is available in 3.1M5 and earlier (3.0 --> 3.1M5)
Can you please log a bug in JIRA in the 'Tools' component category to add support for
Eclipse 3.1M6 for the UI plug-in, mentioning the missing class in 3.1M6?

On the other side, I cannot find the class
'StartDerbyServerLaunchConfigurationDelegate' in any jar of the eclipse
plugins on my machine.. which seems to be the real problem, as written
in the log file.
I run the version 3.1M6.. is this class available in previous milestones ?
