Java 6 is dead and frankly so is Java 7. IBM may still support their own JVMs... I'm not in a position to know. There may be a bug in the Java runtime that is causing problems for you. At least make sure you are running the absolutely latest version of Java 6 that you can get from IBM for AIX. Are you able to at least test with Java 8 to see if there is any improvement? - -chris -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org iQIcBAEBCAAGBQJVktjBAAoJEBzwKT+lPKRYLZIP+gM+NCqQ89hlmiaFPX2wkM3q awLKUfSL7oeAtfbYGneikLqesfkJSZ4DSQhCapdB8XlLsfFvlLQ20roNzd6JHEa/ LufAtuSTn5Tm2gi0iI1SwrKYvZjZDwehEGi82n5qIBvP3JbYxu7MYWoLIdbyNzH5 5buPvRNR+Qft9saektlxlo8MqjetjMQ7vwPhGy4jFcq730goP4iNrmZ+tUUmoyA3 aIkuu58sH3XZnCFyULv0hNSo5lBulgv9lYIJN0uszf1mDXNgD4TcF/J3BQDRdCUC OjxabU6uYTBhfO9BRVGuUXwadAYmqCkC+xmKykPkX3QIM5CedV3wKA0kHu+e32Cz xSVyMgI6LC2urpxDGqTZDGUdE/YbNQ0UEzMAL5oFoTDagGv9rTt0zkATIhhABae5 IY8jtEUGuizo1Hbj7DMmFVO/qZ/lgVb2f8IzZPsBCwqxlA2k3pLuta0igb/eFUWX NTSOcEOKzy8Zg5QyDOIWFp3omOPgiNJwGLDEXi8w5UNa6eJCbyFgcUGuROLLmxsU DEkQbDUQf1g4Z6T7CqV0bmW+Gic/u1AKzibO+wmR7iHbtxP5RW8ytcxFVINE74zq Kt56GKSl7FBZKAUq8nBldeAdCRYWK0CjfTVrAr0iaJfmWl9gODMCFimBJq3hSrCH T7fhd+5uS/2ZwgNtZuDw =4lSg -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
