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.
