[jdk8u-dev] RFR: 8224267: JOptionPane message string with 5000+ newlines produces StackOverflowError

Hi all,

This is a parity backport with Oracle's 8u461, OpenJDK 8u462 is affected. Please see [JDK-8224267](https://bugs.openjdk.org/browse/JDK-8224267). The commit [46251bc6](https://github.com/openjdk/jdk/commit/46251bc6e248a19e8d78173ff8d0502c68ee1acb) didn't apply cleanly as JDK-8049870 hasn't been backported to jdk8u-dev. The paths have been changed to the 8u path scheme. The test passes with the fix and fails otherwise.

Thanks!
