SSLv3 по умолчанию отключена в JRE/JDK с билдов:
- Java 8 update 31
- Java 7 update 75
- Java 6 update 91
Некоторые платежные системы не работают через TLS, а требуют SSLv3. Т.е. при обновлении Java они перестают работать. Чтобы включить поддержку SSLv3 обратно нужно в <JRE_HOME>/lib/security/java.security убрать из параметра jdk.tls.disabledAlgorithms значение "SSLv3".
SSLv3 is disabled by default
Starting with JDK 6u91 release, the SSLv3 protocol (Secure Socket Layer) has been deactivated and is not available by default. See the java.security.Security property jdk.tls.disabledAlgorithms in <JRE_HOME>/lib/security/java.security file.
If SSLv3 is absolutely required, the protocol can be reactivated by removing "SSLv3" from the jdk.tls.disabledAlgorithms property in the java.security file or by dynamically setting this Security property to "true" before JSSE is initialized.
It should be noted that SSLv3 is obsolete and should no longer be used.
