We have a legacy Java site (JRE 1.4.2/Tomcat 4.1/Apache -- all very legacy versions) that processes payments through a likewise legacy version of PayFlow Pro, and were concerned when PayPal recently notified us that support for SSL 3.0 would be ending.
The reason is that we cannot actively develop anything related to checkout on our site due to the lack of a functional development environment (checkout functionality has been broken on our development environment since before my time with the company).
I reached out to our hosting provider with this issue, and they immediately disabled SSL 3.0 on our Apache server. I tested the site via Qualys' service (http://ssllabs.com), and it confirmed that SSL 3.0 is not supported, and several test checkouts I performed worked perfectly.
However, I tried another test checkout this morning, and an unspecified error (see partial stack trace from catalina.out below) caused the VM to crash:
An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : 11 occurred at PC=0x9C1C1AB4
Function=__umoddi3+0x0
Library=/home/tomcat/bin/libpfpro.so
I'm guessing that there's some sort of issue with the libpfpro.so library, but I have absolutely no idea how to approach fixing it, since we don't have an in-house Java developer, and the previous developer has stated in the past that the site's configuration is a bit of a mystery.
I'm looking, either, for some direction as to how to fix the "unexpected exception" due to the PayFlow Pro library or some resources to help us locate on-demand Java expert(s) that may be able to help us resolve this.
