I am trying to debug logstash-2.2.2 in Eclipse, and I cannot figure out
the version of JRuby that came with it. Does below output say 1.7.23, or
jruby 1.7.23 (1.9.3p551) 2015-11-24 f496dd5 on Java HotSpot™ 64-Bit
Server VM 1.8.0_73-b02 +jit [Windows 7-amd64]
I am getting compiler errors that may be caused by using JRuby 1.7, but
adding -Xcompat.version=1.9 did not work.
