RFR: 8224267: JOptionPane message string with 5000+ newlines produces StackOverflowError

[Prasanta Sadhukhan]

BasicOptionPaneUI.addMessageComponents() uses recursion to split message strings at newlines, generating a StackOverflowError when the message string contains an unusually large number of newlines.
Fixed by catching StackOverflow and ignoring so that application is not stuck.
