Issue Summary

In Bitbucket 8.1, exceptions thrown by command handlers' process() method are consumed, whereas in Bitbucket 7 they are wrapped and propagated to com.atlassian.bitbucket.scm.Command.call() and therefore can be handled appropriately.

By adding breakpoints in the Bitbucket source it was determined that BioStdioHandler.RemoteWatchdog.reportError is called, storing the exception. However BioStdioHandler.onComplete() is never called, so the exception is not re-thrown.

Steps to Reproduce

1. See above

Expected Results

Exceptions thrown in CommandOutputHandler.process() method are propagated (like in Bitbucket 7) and can be handled

Actual Results

The exceptions are not propagated since, as mentioned above, BioStdioHandler.onComplete() is never called

Workaround

No workaround available at the moment.
