SSL Handshake exception - RESTEASY004655

I am trying to figure out why am having this type of exception all over the log file!!!!

Looking on some internet posts, apparently they talk about network interruption !!!

javax.ws.rs.ProcessingException: RESTEASY004655: Unable to invoke request at org.jboss.resteasy.client.jaxrs.engines.ApacheHttpClient4Engine.invoke(ApacheHttpClient4Engine.java:287) at com.agfa.orbis.core.client.service.rest.ClientHttpEngineWrapper.invoke(ClientHttpEngineWrapper.java:59) at org.jboss.resteasy.client.jaxrs.internal.ClientInvocation.invoke(ClientInvocation.java:436) at org.jboss.resteasy.client.jaxrs.internal.ClientInvocation.invoke(ClientInvocation.java:471) at com.agfa.hap.base.server.ServerValidationRestCalls.getDatabase(ServerValidationRestCalls.java:51) at com.agfa.hap.base.server.ServerValidationRestCalls.getDatabaseIdentifier(ServerValidationRestCalls.java:101) at com.agfa.hap.base.server.ClientServerDBConsistence.determineServerDBIdentifier(ClientServerDBConsistence.java:148) at com.agfa.hap.base.server.ClientServerDBConsistence.isClientAndIndividualServerDBIdentical(ClientServerDBConsistence.java:230) at com.agfa.hap.base.server.ServerConnectionManager.isClientAndIndividualServerDBIdentical(ServerConnectionManager.java:329) at com.agfa.hap.base.server.ServerConnectionManager.checkAppServerDatabaseConsistency(ServerConnectionManager.java:286) at com.agfa.hap.base.server.ServerConnectionManager.executeServerConnectionReview(ServerConnectionManager.java:202) at com.agfa.hap.base.server.ServerConnectionManager.checkServerConnection(ServerConnectionManager.java:175) at com.agfa.hap.base.server.ServerConnectionManager$2.run(ServerConnectionManager.java:259) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:992) at sun.security.ssl.SSLSocketImpl.performInitialHandshake(SSLSocketImpl.java:1375) at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1403) at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1387) at org.apache.http.conn.ssl.SSLSocketFactory.connectSocket(SSLSocketFactory.java:535) at org.apache.http.conn.ssl.SSLSocketFactory.connectSocket(SSLSocketFactory.java:403) at org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection(DefaultClientConnectionOperator.java:177) at org.apache.http.impl.conn.ManagedClientConnectionImpl.open(ManagedClientConnectionImpl.java:304) at org.apache.http.impl.client.DefaultRequestDirector.tryConnect(DefaultRequestDirector.java:611) at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:446) at org.apache.http.impl.client.AbstractHttpClient.doExecute(AbstractHttpClient.java:863) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:82) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:57) at org.jboss.resteasy.client.jaxrs.engines.ApacheHttpClient4Engine.invoke(ApacheHttpClient4Engine.java:283) ... 15 more Caused by: java.io.EOFException: SSL peer shut down incorrectly at sun.security.ssl.InputRecord.read(InputRecord.java:505) at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:973) ... 28 more 

Any clue about such exception ?

It isn't a network interruption (or an invalid / expired SSL cert). What has happened is the remote end has closed the connection in the middle of the SSL connection negotiation. Most likely it is because there is a mismatch between requested and supported protocol versions or crypto algorithms.

You need to turn on debugging messages for the SSL protocol stack; e.g. using -Djavax.net.debug=all. That will give you more information, and from that you can figure out what you need to do to fix the mismatch.
