Working with JREs
    
    
      You can install as many
      different Java Runtime Environments (JREs) as you like. JREs are used to
      run and debug java programs. Your JREs are managed on the Installed
      JREs preference page.
    
    
      A JRE definition consists of:
    
    
      - The type of the JRE (e.g. Standard VM or Standard 1.x.x VM)
      
- A name
      
- The location where the JRE is installed
      
- The system libraries containing the Java system classes (like
      java.lang.Object). Optionally, the system libraries can be associated
      with:
      
      
- Other information needed by the VM to build, run and debug
      applications.
      
      You can switch the
      default JRE for the workbench. The default JRE is used by default when
      building, running, and debugging applications. Alternatively, projects
      may specify a specific
      JRE that they should be built and run with.
