Java API 2.0.3 returns "Could not decode cluster info" from ClusterManager.getBuckets() on Windows 7

Customer is reporting that after reinstalling Couchbase Server 3.0.1, they started to receive the following exception:

Exception in thread "main" com.couchbase.client.java.error.TranscodingException: Could not decode cluster info.

This is on Windows 7 with CB 3.0.1 (and they tried 3.0.2 also) and Java 2.0.3 (and 2.0.2)

I have not been able to reproduce. A wireshark trace on a Windows system does not catch localhost traffic.

Here is the trace:
