SSLSessionContext.setSessionTimeout() documentation could be updated

Name: ktR10099 Date: 12/10/2003



According to the spec for
javax.net.ssl.SSLSessionContext.setSessionTimeout(int seconds) "If the
timeout limit is set to 't' seconds, a session exceeds the timeout limit
't' seconds after its creation time. When the timeout limit is exceeded
for a session, the SSLSession object is invalidated..." Please find below
example, demonstrating that this does not work for current java
implementation. session.isValid() should return false after timeout, but
it still returns true.
