NullPointer with HttpClient 3.1 + IBM 1.4.1 JRE

All,

I did some work integrating with a credit card authorizer over https 
using the HttpClient 3.1. Proper connection timeouts are very important 
to the authorizer. All of my testing, with a sun jdk worked fine, 
however when I switched to the production JDK (ibm 1.4.1) I get a null 
pointer in the ibm jsse implementation if i set a connection timeout 
(see log below). I realize this is NOT a problem with HttpClient but 
rather with the ibm jsse implementation, but does anyone know a work 
around for it.

Thanks
Steve

Hi Steve,

Early releases of IBM JSSE are known to be very buggy. Please make sure
the JVM is at the latest patch level. Alternatively, consider upgrading
to a newer IBM JDK (1.4.2.x or 1.5.0.x). Those versions should come with
a better JSSE implementation. You may also consider upgrading to
HttpClient 4.0 as the last resort. HttpClient 4.0 has a much more
flexible API compared to 3.x and it should be easier to customize its
connection management code so that it does not trigger any of IBM JSSE
bugs.

Hope this helps

Oleg
