After updating Java to Update 45 - you can no longer login to UCSM (UCS Manager)

You may see one of two errors:

Login Error: java.io.IOException: Invalid Http response**
Login Error: java.io.IOException: Server returned HTTP response code: 400 for URL:** [https://x.x.x.x:443/nuova](https://x.x.x.x:443/nuova)

Cisco Bug ID: CSCuj84421

This is due to a change introduced in Java

The solution posted is to rollback to Update 25. Rolling back to Update 40 also works.
