javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake in applet

Question

In my web application, I am using a applet which is signed jar and this applet was working fine before jre 1.6 and 1.7. But after security popup and blocking error of applet we

Answer 1

We are having this same issue. I believe this is a bug in the way Java implemented TLS 1.2 for SSL.

According to their documentation, https://blogs.oracle.com/java-platform-group/entry/java_8_will_use_tls, they claim that by enabling TLS 1.2, it is backwards compatible with older versions.

However, this is not the case. When TLS 1.2 is disabled, we no longer get the "Remote host closed connection during handshake" error.

TLS 1.2 support can be turned off from the Advanced Settings in the Java Control Panel.

Once this is done, the applets will work.

Answer 2

In our case we have been getting same exception. But for both java1.6 and 1.7 Our environment was as follows:

• jbossAS5.1 with deployed web application and one applet in that web application
• apache web server2.2.1 requiring client certificate(self signed)
• on client side mozilla and explorer with imported client certificate, jre with imported client certificate

In jre control panel we disabled SSL2 client hello format and also disabled SSL3 and TLS1.2 We left enabled only TLS1.0 and TLS1.1 and everything worked fine since that time.
