We handle that here and categorize it as part # of `failures` rather than letting it fall through and be categorized as part of # `other_errors`. failures << e rescue Support::AllExceptionsExceptOnesWeMustNotRescue => e # While it is normally a bad practice to rescue `Exception`, it's important we do # so here. It's low risk (`notify_aggregated_failures` below will re-raise the exception, # or raise a `MultipleExpectationsNotMetError` that includes the exception), and it's # essential that the user is notified of expectation failures that may have already # occurred in the `aggregate_failures` block. Those expectation failures may provide # important diagnostics for understanding why this exception occurred, and if we simply # allowed this exception to be raised as-is, it would (wrongly) suggest to the user # that the expectation passed when it did not, which would be quite confusing. other_errors << e end end notify_aggregated_failures end

On JRuby 9.1.x.x and before, ‘caller` and `raise` produce different backtraces with regards to `.java` stack frames. It’s important that we use ‘raise` for JRuby to produce a backtrace that has a continuous common section with the raised `MultipleExpectationsNotMetError`, so that rspec-core’s truncation logic can work properly on it to list the backtrace relative to the ‘aggregate_failures` block. :nocov:
# File lib/rspec/expectations/failure_aggregator.rb, line 84 def assign_backtrace(failure) raise failure rescue failure.class => e failure.set_backtrace(e.backtrace) end
