      Pig 0.14.3
      Java 1.7.0 - see below

      Description

      If you build pig against java patch version 79, it works, but pig built against 85 does not. Here is the code to reproduce.

      $ java -version
      java version "1.7.0_85"
      OpenJDK Runtime Environment (rhel-2.6.1.3.el6_6-x86_64 u85-b01)
      OpenJDK 64-Bit Server VM (build 24.85-b03, mixed mode)
      

      Then add this code to `query.pig`. Notice that we're registering a ruby UDF and that's all.

      SET job.priority 'normal'; REGISTER ./utility_udfs.rb using jruby AS utilities;
      

      Make sure you build pig against this java version.

      $ant
      

      Then run the job

      $pig -x local -F query.pig
      

      You will get this error

          at org.apache.pig.scripting.jruby.PigJrubyLibrary.load(PigJrubyLibrary.java:76)
      

      If you're on this Java version, everything runs fine

      $ java -version
      java version "1.7.0_79"
      OpenJDK Runtime Environment (rhel-2.5.5.3.el6_6-x86_64 u79-b14)
      OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)
      

      java 1.7.0_85 also breaks with pig 0.15
