Subject [jira] [Commented] (ACCUMULO-3789) Code compiled against 1.6 lexicoders can't run in 1.7

Josh Elser commented on ACCUMULO-3789:
--------------------------------------

bq. I didn't realize it auto-assigned to you, Josh. I'm happy to take it on if your plate
is full.

Oh, no, I assigned it to myself because I saw it was unassigned. I'm just trying to get a
1.7.0 RC this weekend so I'll be burning some extra oil anyways. If you get to it, please
feel free to put up a patch. I don't want to stomp on your toes.

Your assessment sounds right to me. I agree that the fix would be to re-add the decode implementations
in the concrete Lexicoders and mark those methods as deprecated. So we can remove them in
the future.

>    Affects Versions: 1.7.0
>         Environment: Development environment
>            Reporter: Russ Weeks
>            Assignee: Josh Elser

> 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.
> h3. 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}}
> h3. Expected Result
> * All unit tests pass
> h3. Actual Result
> * The unit test "TestLexicoderCompatibility" fails with the error:
> {noformat}
> java.lang.NoSuchMethodError: org.apache.accumulo.core.client.lexicoder.LongLexicoder.decode([B)Ljava/lang/Long;
> 	at lexicoder.TestLexicoderCompatibility.testLexicoderBackwardsCompatibility(TestLexicoderCompatibility.java:20)
> 	[snip]
> {noformat}
> * Switching the {{testRuntime}} dependency to 1.6.1 instead of 1.7.0-SNAPSHOT will cause
the test to pass.
