Solution

  • If you are getting a NoSuchMethodError, that means that you have a runtime version incompatibility problem. Some part of the codebase depends on1 a version of Base64 that has a method called decodeBase64 that takes a single String argument. But the version of the class that has been loaded doesn't have that method.

    There is a clue in the javadoc for the method. It says that the method was added to the Base64 in version 1.4 of the API. So check the JAR files that are deployed to see if there is an older (pre 1.4) version of the Apache Commons Codec JAR on the runtime classpath.

    1 - It could be a static dependency; i.e. a normal method call. It could also be a dynamic dependency; e.g. attempting to lookup the method using reflection.
