    ClassFormatError on Websphere 6.1 on iSeries

      Hi

      We have Seam 1.2.1GA POJO app that works fine on Websphere 6.1 on Windows. However the same EAR file fails on Websphere 6.1 on IBM's iSeries server. javassist throws a ClassFormatError when loading the the first Seam component for the application. Here's the exception...

      Here's the interesting part...typically ClassFormatError would also provide the message indicating the cause for failure, but in this case it just displays a sequence of numbers...

      Both on windows and the iSeries box we are using IBM's Java 1.5 JRE. Also i'm using javassist 3.4. Anybody can shed any light on what the numbers are?

      Thanks.
