It isn't clear that this error is due to use of Xalan. It might be related to other parts of your web app. Just curious, how Xalan is packaged within your web app?
I am using xalan 2.7.0 in my web application and while deploying my application in jBoss6.1.0.Final on IBM AIX7 with IBM JDK I am getting VerifyError. IBM JDK installed version is follows;
java version "1.6.0"
Java(TM) SE Runtime Environment (build pap6460sr14-20130705_01(SR14))
IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 AIX ppc64-64 jvmap6460sr14-20130704_155156 (JIT enabled, AOT enabled)

Not sure where to report this issue.
