RFR: JDK-8249699: java/io/ByteArrayOutputStream/MaxCapacity.java should use @requires instead of @ignore

Hi, Could I please get reviews and a sponsor for: webrev: http://cr.openjdk.java.net/~fguallini/8249699/webrev.00/ <http://cr.openjdk.java.net/~fguallini/8249699/webrev.00/> Testbug: https://bugs.openjdk.java.net/browse/JDK-8249699 <https://bugs.openjdk.java.net/browse/JDK-8249699> The test was ignored due to ‘huge memory requirements’, but with the jtreg current version, tests can be only run when system requirements are satisfied as opposed to being always excluded. It runs and passes in Mach5 Thanks -Fernando
