java - NoSuchMethodError: com.google.common.base.Stopwatch.createStarted()Lcom/google/common/base/Stopwatch

Question

My app is throwing NoSuchMethodError: com.google.common.base.Stopwatch.createStarted()Lcom/google/common/base/Stopwatch error. Not sure why, because 16.0.1 do contain that class, I've checked. From what I have researched, it looks like this is a bug?

I also have this code for refernence, though I think this is not the issue:

    FirewallRule rule = new PeriodicFirewallCounterRule(60, TimeUnit.SECONDS, new IpAddressCountingPolicy());
    ((PeriodicFirewallCounterRule)rule).addHandler(new RateLimitationHandler(new UniqueLimitPolicy(10)));
    FirewallFilter firewallFiler = new FirewallFilter(getContext(), list(rule));
    firewallFiler.setNext(ma);

My app is using Restlet APISpark:

  <dependency>
      <groupId>org.restlet.gae</groupId>
      <artifactId>org.restlet.ext.apispark</artifactId>
      <version>${version.restlet}</version>
  </dependency>

When running and accessing the REST api of the app, it throws this error:

[INFO] Caused by: java.lang.NoSuchMethodError: com.google.common.base.Stopwatch.createStarted()Lcom/google/common/base/Stopwatch;

When using the extension org.restlet.ext.apispark, the guava dependency retrieved has the version 16.0.1.

Downloading: http://maven.restlet.com/com/google/guava/guava/16.0.1/guava-16.0.1.jar
Downloading: http://repo.maven.apache.org/maven2/com/google/guava/guava/16.0.1/guava-16.0.1.jar
Downloaded: http://repo.maven.apache.org/maven2/com/google/guava/guava/16.0.1/guava-16.0.1.jar (2176 KB at 711.7 KB/sec)

It comes within an application created from scratch with the following maven configuration:

I integrated your code and it works fine on my side. No exception is thrown...

I think that an older version of Guava comes from another dependency. If you use Maven, you should identify where this old guava version comes from and perhaps add an exclude within the corresponding dependency. I hope that it will fix your problem...

Hope that helps you, Thierry
