Sample code Throwable vs RubyException
# The following block logs java.lang.Throwable correctly: http://www.slf4j.org/api/org/slf4j/Logger.html#error(java.lang.String,%20java.lang.Throwable)
begin
Java::ComGoogleCommonBase::Preconditions.check_argument(false, "I don't like you")
rescue => e
logger = Java::OrgSlf4j::LoggerFactory.get_logger('logger')
logger.error("This works", e)
end
# However RubyException is not a throwable and treats it as a java.lang.Object: http://www.slf4j.org/api/org/slf4j/Logger.html#error(java.lang.String,%20java.lang.Object...)
begin
raise "error"
