После обновления до Java 7u211 требуется в 3 раза больше времени для входа в базу данных и даже в другие внешние приложения, где требуется расшифровка пароля.

1) Всего 19 потоки, ожидающие подключения к базе данных в JBoss. Это неоправданно много при нормальных обстоятельствах:

2) Все эти 19 потоков ожидают трех блокировок (выделено: 0x00000006010ae1b0, 0x00000006010aa3c8, 0x0000000600bafa50). Эти 3 блокировки используются другими 3 потоками:

Line 279: - locked <0x00000006010aa3c8> (a org.jboss.jca.adapters.jdbc.local.LocalManagedConnectionFactory)
Line 1496: - locked <0x0000000600bafa50> (a org.jboss.jca.adapters.jdbc.local.LocalManagedConnectionFactory)

3) Эти 3 потока имеют почти идентичный стек:
