      Description

      Code which was built against the 1.6 Lexicoders will fail with a NoSuchMethod error when run against the 1.7 jars.

      Test case is attached. Sorry it depends on Gradle, the build file is pretty trivial.

      Steps to reproduce

      • Deploy accumulo 1.7.0-SNAPSHOT jars to local maven repository, I did mvn -DskipTests -Dfindbugs.skip=true install on commit 31dd5ca
      • Untar attached file TestLexicoderCompat.tar.gz, run gradle clean test

      Expected Result

      • All unit tests pass

      Actual Result

      • The unit test "TestLexicoderCompatibility" fails with the error:
        java.lang.NoSuchMethodError: org.apache.accumulo.core.client.lexicoder.LongLexicoder.decode([B)Ljava/lang/Long;
        	at lexicoder.TestLexicoderCompatibility.testLexicoderBackwardsCompatibility(TestLexicoderCompatibility.java:20)
        	[snip]
        
      • Switching the testRuntime dependency to 1.6.1 instead of 1.7.0-SNAPSHOT will cause the test to pass.
