Jtreg build is failing

[Mani Sarkar]

Hi all,

Recently jtreg stopped building on our build farm, checking the logs we got
(this version uses jdk9 as one of the jdks during the build process):

-compile-jtreg.usage:
    [mkdir] Created dir: /scratch/jenkins/workspace/jtreg/build/jtreg
     [java] Executing
'/opt/java/sdk/Oracle/x86_64/jdk1.8.0_102/jre/bin/java' with
arguments:
     [java] '-Dprogram=jtreg'
     [java] '-classpath'
     [java] '/scratch/jenkins/workspace/jtreg/build/classes:/scratch/jenkins/workspace/jtreg/jtharness/lib/javatest.jar:/scratch/jenkins/workspace/jtreg/junit/junit.jar:/scratch/jenkins/workspace/jtreg/jh2.0/javahelp/lib/jh.jar'
     [java] 'com.sun.javatest.regtest.Main'
     [java] '-help'
     [java] 'all'
     [java]
     [java] The ' characters around the executable and arguments are
     [java] not part of the command.
     [java] Output redirected to
/scratch/jenkins/workspace/jtreg/build/jtreg/usage.txt
