I am having issues with Aspose.Words.jdk16.jar using IBM JIT 1.6. Using IBM JVM without JIT or Sun JVM the problem does not appear
According to the mail quoted below, you have a temporary version which solves this issue - can I get hold of this version?
IBM JIT conflicts with optimization of Aspose.Words jar. This issue will be fixed in the next Aspose.Words release (scheduled on September). For temporary workaround I have emailed you Aspose.Words.jdk16.jar without optimization that should work with IBM JIT. Please, check your e-mail.
