When WorkArea attempts to load the BigInteger/BigDecimal class, we load a byte[]. The "[" in the class name indicates array syntax. That's not intended to be allowed in a class loading operation, but IBM's Java implementation has tolerated it in the past. That changed in fixpack FP5 - in an attempt to more strictly interpret the specification, that syntax is no longer allowed and results in a ClassNotFoundException. The CNFE is being swallowed by the JDK, but it leads to the exception we are seeing.
Problem conclusion
The fix for this APAR is in WorkArea's classloading implementation. The fix for this APAR is currently targeted for inclusion in Service Level (Fix Pack) 9.0.0.9 and 8.5.5.14.
