As said in the description The code must contain a Leetspeak class inherited from an Encoder abstract class and containing an encode(String) method returning itself the encoded String. so if you removed the Encoder class from the initial solution this will cause this error.

My tests are passing but when I try to submit my code I get the following error:

/tmp/java5462391155140846081/EncodeTest.java:8: error: cannot find symbol
Encoder myEncoder = null;
^
symbol: class Encoder
location: class EncodeTest
1 error

java.lang.RuntimeException: /tmp/java5462391155140846081/EncodeTest.java:8: error: cannot find symbol Encoder myEncoder = null; ^ symbol: class Encoder location: class EncodeTest 1 error at codewars.runners.java$compile_BANG_.doInvoke(java.clj:25) at clojure.lang.RestFn.applyTo(RestFn.java:137) at clojure.core$apply.invoke(core.clj:624) at codewars.runners.java$fn__162.invoke(java.clj:71) at clojure.lang.MultiFn.invoke(MultiFn.java:227) at codewars.runners$run.invoke(runners.clj:22) at codewars.core$_main$fn__608.invoke(core.clj:30) at clojure.lang.AFn.call(AFn.java:18) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.lang.Thread.run(Thread.java:745)

Any thoughts about what is happening? :(
