Symptoms

The following appears in the atlassian-fisheye-YYYY-MM-DD.log during the setup of an SVN repository that uses SSL:

com.cenqua.fisheye.rep.RepositoryClientException: org.apache.subversion.javahl.ClientException: svn: E175002: handshake alert:  unrecognized_name

Cause

Java 7 introduced SNI support which is enabled by default. Certain misconfigured servers send an "Unrecognized Name" warning in the SSL handshake which is ignored by most clients, except for Java.

Resolution

1. Add the following to the FISHEYE_OPTS environment variable:

   -Djsse.enableSNIExtension=false
   

2. Restart your Fisheye instance.
