OutputStreamAppender.start Called Twice

[paulespinosa]

Using logback 1.1.7, I get the error message "No output stream set for the appender". By looking at web-logback's code, it appears that OutputStreamAppender.start() is being invoked twice within BrowserConsoleAppender.start():

1. A thread invokes OutputStreamAppender.start() but calls setOutputStream first.
2. Main thread invokes OutputStreamAppender.start() but doesn't call setOutputStream.

Possibly due to a race condition, the main thread is invoking OutputStreamAppender.start() before the secondary thread gets to call setOutputStream. But, it seems that having two calls to OutputStreamAppender.start() is unnecessary.
