  • FULL PRODUCT VERSION : Java(TM) SE Runtime Environment (build 1.7.0_45-b18) Java HotSpot(TM) Client VM (build 24.45-b08, mixed mode, sharing) ADDITIONAL OS VERSION INFORMATION : Microsoft Windows [Version 6.1.7601] A DESCRIPTION OF THE PROBLEM : This happens with jre 1.7.0_45. This *does not* happen with jre 1.7.0_05. This does happen with jre 1.6.0_35 I'm using "Apache/2.2.24 (Unix) DAV/2 PHP/5.3.26 mod_ssl/2.2.24 OpenSSL/0.9.8y" on Mac OS X 10.8.5 as the webserver. My config file looks like this Listen 443 <VirtualHost *:443> DocumentRoot /path/to/my_files/ SSLEngine on SSLProtocol SSLv3 SSLCertificateFile /path/to/test.cert SSLCertificateKeyFile /path/to/test.key </VirtualHost> This limits connections to be SSLv3 only. When run with jre 1.7.0_45 I get the following output: java HttpsConnectionExample https://192.168.0.6/ Vendor 'Oracle Corporation' URL 'http://java.oracle.com/' Version '1.7.0_45' javax.net.ssl.SSLException: Received fatal alert: bad_record_mac at sun.security.ssl.Alerts.getSSLException(Unknown Source) at sun.security.ssl.Alerts.getSSLException(Unknown Source) at sun.security.ssl.SSLSocketImpl.recvAlert(Unknown Source) at sun.security.ssl.SSLSocketImpl.readRecord(Unknown Source) at sun.security.ssl.SSLSocketImpl.performInitialHandshake(Unknown Source) at sun.security.ssl.SSLSocketImpl.startHandshake(Unknown Source) at sun.security.ssl.SSLSocketImpl.startHandshake(Unknown Source) at sun.net.www.protocol.https.HttpsClient.afterConnect(Unknown Source) at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at java.net.HttpURLConnection.getResponseCode(Unknown Source) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getResponseCode(Unknown Source) at HttpsConnectionExample.main(HttpsConnectionExample.java:86) I get similar output from jre 1.6.0_35: java HttpsConnectionExample https://192.168.0.6/ Vendor 'Sun Microsystems Inc.' URL 'http://java.sun.com/' Version '1.6.0_35' javax.net.ssl.SSLException: Received fatal alert: bad_record_mac at com.sun.net.ssl.internal.ssl.Alerts.getSSLException(Unknown Source) at com.sun.net.ssl.internal.ssl.Alerts.getSSLException(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.recvAlert(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.readRecord(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.performInitialHandshake(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.startHandshake(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.startHandshake(Unknown Source) at sun.net.www.protocol.https.HttpsClient.afterConnect(Unknown Source) at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at java.net.HttpURLConnection.getResponseCode(Unknown Source) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getResponseCode(Unknown Source) at HttpsConnectionExample.main(HttpsConnectionExample.java:86) However this works with jre 1.7.0_05: java HttpsConnectionExample https://192.168.0.6:443/ Vendor 'Oracle Corporation' URL 'http://java.oracle.com/' Version '1.7.0_05' Response Code: 200 I've taken and will try to attache wiresharks of the ssl traffic for each of the 3 jre versions I've run this against. I'm not an SSL expert, but I have noticed the version of the Client Hello seems to differ between jre versions: 1.7.0_45 -> SSLv3. 1.7.0_05 -> SSLv3. 1.6.0_35 -> SSLv2. REGRESSION.
