[FDS-131] Debugging connection fails with “resource temporarily unavailable” or “target failed to handshake” message

Symptom

When trying to debug against a 1.7 JVM you receive a handshake error such as:

• Debugger failed to attach: recv failed during handshake: Resource temporarily unavailable
• com.intergral.fusiondebug.client.model.FDModelConnectionException: java.net.SocketException: Software caused connection abort: socket write error
• com.intergral.fusiondebug.client.model.FDModelConnectionException: java.io.IOException: Target failed to handshake

Background

Oracle/Sun changed the JVM debug connection handshake in the 1.7 JVM series; somewhere after update 2.
