Pinned topic MessageDigest MD5 / SHA256 implementation not found on IBM WAS 7

‏2013-12-24T06:37:12Z |


We have a Java application that performs inline PDF SHA2 signing using iText & BouncyCastle hosted on AIX 6.1.

Things were working fine until this was hosted on IBM WAS 6.1. On migration to IBM WAS 7 FP 19 or FP 29, the following errors started occuring INTERMITTENTLY.

MessageDigest MD5 implementation not found / MessageDigest SHA256 implementation not found

Inspite of explicitly adding BouncyCastleProvider to the list of providers using Security.addProvider, the issue still persists.

Any ideas on this would be of great assistance to us.
