Answer 1

Another option is:

• Project > Properties > Java Build Path
• Select Libraries tab
• Select the troublesome JRE entry
• Click Edit button
• Choose an alternate JRE
• Click Finish button

Pointing the project at your installed JRE might be a better choice than renaming your JRE to match the old project code.
