      Description

      When creating a MongoClient with mongo+srv scheme and that java.naming.provider.url JNDI property is set to a file URL, the driver throws

       

      com.mongodb.MongoClientException: Unable to support mongodb+srv// style connections as the 'com.sun.jndi.dns.DnsContextFactory' class is not available in this JRE. A JNDI context is required for resolving SRV records.com.mongodb.MongoClientException: Unable to support mongodb+srv// style connections as the 'com.sun.jndi.dns.DnsContextFactory' class is not available in this JRE.

      There are two issues here. First is that the exception message is misleading. DefaultDnsResolver.createDnsDirContext assumes all NamingException}}s are caused by the unavailability of DnsContextFactory. Checking the causing exception, it fails because I have this JNDI property

       

      java.naming.provider.url=file:/tmp

      which is not supported by the DnsContextFactory.

       

      To reproduce:

         1. Add jndi.properties file to the classpath with content

      java.naming.provider.url=file:/tmp

         2. Run the following code

      MongoClients.create( "mongodb+srv://server.example.com/" );
