-----------------------------------

             Summary: Java patch version breaks Ruby UDF loading
                 Key: PIG-4640
                 URL: https://issues.apache.org/jira/browse/PIG-4640
             Project: Pig
          Issue Type: Bug
         Environment: CentOS 6.5
Pig 0.14.3
Java 1.7.0 - see below
            Reporter: Edward Winslow


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;
}}

Then run the job...this example is slightly convoluted, but I'm not good enough with pig to shrink it down, sorry

{{
$pig local -F query.pig
}}

You will get this error

}}

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)
}}

I don't know if the issue persists in pig 0.15 but I can test as needed.
