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"

Don't use this
# Workaround for IO.popen.readlines being allowed to block indefinitely even if
# wrapped in a Timeout::timeout call.
#
# Test case:
# $ time jruby -rtimeout -e "timeout(1) { IO.popen('sleep 10').readlines }"
# * Propagating errors executed in the block
# * Thread.raise experiences a TypeError because it cannot convert a java Exception into a ruby Error so I've added handling any errors raised from the java code to be propagated correctly
# * Renamed some variables so that they matched
