If an exception is raised by code triggered from Bootstrap class, only its message (and the message of the possible cause stack) is displayed, not the full stack trace.

This means that if for example some plugin reads a System property that it expects to be numeric but which is accidentally set as empty, you only see something like this

{2.0.0-SNAPSHOT}: Startup Failed ...
- NumberFormatException[For input string: ""]

I propose the whole stack trace would be displayed in these cases, either on System.err when no logging is configured or on ERROR level via log4j. This would make these kinds of configuration errors loads easier to debug, with the small price of uglier error messages.

Pull request is coming up.

Show stacktrace of startup exception

Whether or not the stacktrace is displayed is controlled by bootstrap
log level setting, so that bootstrap: DEBUG displays the stack trace on
output, like it does on log

Closes #5102
