Error description
Error Message: java.lang.ArrayIndexOutOfBoundsException: Array index out of range: 64 . Stack Trace: javax.net.ssl.SSLException: java.lang.ArrayIndexOutOfBoundsException: Array index out of range: 64 at com.ibm.jsse2.o.a(o.java:10) at com.ibm.jsse2.SSLSocketImpl.a(SSLSocketImpl.java:216) at com.ibm.jsse2.SSLSocketImpl.a(SSLSocketImpl.java:864) at com.ibm.jsse2.SSLSocketImpl.a(SSLSocketImpl.java:618) at com.ibm.jsse2.SSLSocketImpl.a(SSLSocketImpl.java:500) at com.ibm.jsse2.SSLSocketImpl.startHandshake(SSLSocketImpl.java:22 0) at com.ibm.net.ssl.www2.protocol.https.c.afterConnect(c.java:184) at com.ibm.net.ssl.www2.protocol.https.d.connect(d.java:40) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpU RLConnection.java:1207) at java.net.HttpURLConnection.getResponseCode(HttpURLConnection.jav a:390) at com.ibm.net.ssl.www2.protocol.https.b.getResponseCode(b.java:29) . The problem happens when the server side uses large DH key (e.g. 2048 bit) in TLSv1/TLSv1.1 key exchange.
Local fix
1. Disable cipher suites which uses DH/DHE key exchange. 2. Use TLSv1.2.
Problem summary
This problem happens because the large pre-master secret generated from 2048 bit DH key was not properly hashed to derive the master secret.
Problem conclusion
A fix is made to IBMJSSE2 and IBMJCE provider to handle large pre-master secret in TLSv1 and TLSv1.1 The associated Hursley RTC Problem Report is 93670 The associated Austin CMVC defect is 116692 The associated Austin APAR is IV73472 JVMs affected: Java 6.0, Java 626, Java 7.0, Java 727 and Java 8 The fix was delivered for Java 6.0 SR16FP5, Java 626 SR8FP5, Java 7.0 SR9FP10, Java 727 SR3FP10 and Java 8 SR1FP10 The affected jar are "ibmjsseprovider2.jar" and "ibmjceprovider.jar". The build level of these jars for the affected releases is "20150604". .
