****************************************************************
If the JAX-WS WS-Security runtime encounters newline
characters in the Base64 encoded text in a SOAP
Security header, an error similar to one of the following may
occur.

the message: org.apache.axiom.om.OMException:

Problem conclusion

The JAX-WS runtime decodes inbound Base64 encoded data using a
table, four bytes at a time.  The data is run through the
table assuming that all the characters contained within the
data are valid Base64 characters.  A newline character is not
valid Base64 character.

However, some web services implementations split all the lines
of Base64 encoded data in their outbound SOAP messages with a
newline character on a fixed boundary; for instance, 76
characters.

In order for WebSphere WS-Security to interoperate properly
with those web services implementations, the newline
characters that occur in the Base64 encoded text must be
tolerated.

The WS-Security runtime is updated to discard newline
characters that exist in the Base64 encoded text.

The fix for this APAR is currently targeted for inclusion in
fix pack 7.0.0.15.  Please refer to the Recommended Updates
