Comment 9 for bug 1482924

Here's a small test class and the results from a few different JVMs I have access to:

import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSocket;

public class TLSVersions
{
  public static void main( String[] args )
  {
    String vendor = System.getProperty( "java.vendor" );
    String version = System.getProperty( "java.version" );

    System.out.println( String.format( "java.vendor\tjava.version\tproto\tenabledProtocols" ) );
    for ( String protocol : new String[]{ "TLSv1.2", "TLSv1.1", "TLSv1", "TLS", "SSL" } )
    {
      try
      {
        SSLContext context = SSLContext.getInstance( protocol );
        context.init( null, null, null );
        SSLSocket socket = ( SSLSocket ) context.getSocketFactory().createSocket();
        String enabledProtocols = join( socket.getEnabledProtocols() );
        System.out.println( String.format( "%s\t%s\t%s\t%s", vendor, version, protocol, enabledProtocols ) );
      }
      catch ( Exception e )
      {
        System.out.println( String.format( "%s\t%s\t%s\t%s", vendor, version, protocol, e.toString() ) );
      }
    }
  }

  private static String join( String[] array )
  {
    if ( array.length == 0 )
    {
      return "";
    }
    StringBuilder sb = new StringBuilder( array[ 0 ] );
    for ( int i = 1; i < array.length; i++ )
    {
      sb.append( ',' ).append( array[ i ] );
    }
    return sb.toString();
  }
}

TL;DR: in 1.8.0_60, which to be clear is the current (binary-only) Oracle release downloaded from java.sun.com for the OS X platform, the default configuration of a SSLSocket created with the generic SSLContext.getInstance("TLS") or SSLContext.getInstance("SSL") includes v1.2 by default. This is not the case in any of the other examples
