ASDM Error: Unconnected socket not implemented

When you receive the following error, while starting ASDM:

ASDM Error: Unconnected socket not implemented

You should look at your Java versions. When you are using Java 6 Update 10 or higher and ASDM 6.1.5 or lower, you will receive this error. There are two workarounds for this problem:

1. Downgrade Java to Java 6 Update 7 or lower;
2. Upgrade ASDM software;

Cisco released an Interim Release (6.1.5.57), which resolves the problem above.
