What is this?

JVM Diagnostic Commands tool - Sends diagnostic command requests to a running Java Virtual Machine. Solaris, Linux, and OS X jconsole: A JMX-compliant graphical tool for monitoring a Java virtual machine. It can monitor both local and remote JVMs. It can also monitor and manage an application.

Contains an older version of the IBM virtual machine when compared IBM SDK, Java Technology Edition, Version 7 Release 1. Version 6 Support for IBM SDK, Java Technology Edition, Version 6 has ended for some platforms unless covered by an extended support contract or embedded in an IBM product that has not reached its own end of service date.
The Oracle SQL developer is NOT supported on 64 bits JDK.To solve it, install a 32 bits / x86 JDK and update your SQL developer config file, so that it points to the 32 bits JDK.
