Ugly backtrace using backquotes on App Engine
---------------------------------------------
Key: JRUBY-4534
URL: http://jira.codehaus.org/browse/JRUBY-4534
Project: JRuby
Issue Type: Bug
Reporter: Rib Rdb
Assignee: Thomas E Enebo
Using backquotes on App Engine results in a stack trace like the one below.
This instance can easily be fixed by catching the exception in
RubyKernel.backquote (in fact it's already trying, it probably just needs a
catch (Throwable t) instead of catch (Exception e)). However looking at the
trace it seems like there's probably lots of other places with this problem.
Perhaps the generated invokers should be changed to catch RuntimeExceptions and
convert them to NativeExceptions?
