cxf, jaxb on AIX/IBM Java - CollisionCheckStack issue

Question

I had the following issue recently in my code. The environment is:

Java(TM) SE Runtime Environment (build pap6470sr1-20120330_01(SR1))

IBM J9 VM (build 2.6, JRE 1.7.0 AIX ppc64-64 20120322_106209 (JIT enabled, AOT enabled))

J9VM - R26_Java726_SR1_20120322_1720_B106209

Throwable occurred: java.lang.ArrayIndexOutOfBoundsException: Array index out of range: -14

This code worked fine on Linux server with Oracle Java 1.7. It also worked on AIX with IBM Java 1.6. But it throws these exceptions when using IBM Java 1.7. I did a research of com.sun.xml.bind.v2.util.CollisionCheckStack.findDuplicate(CollisionCheckStack.java:133) And found some looking similar issues/answers, such as:

http://mydevtoolbox.blogspot.com/2013/07/jaxb-marshaller-no-threadsafe-error.html, which recommends “Create a Marshaller and Unmarshaller per request”

I don’t explicitly use Marshaller/Unmarshaller – it looks like CXF/JAXB issue on Java 1.7.

Any thoughts, insights, opinions are greatly appreciated.

Answer 1

Can you try using JAXB 2.2.4 based jars for IBM Java 1.7 and see if that solves the issue?

Answer 2

We had this issue after upgrading JAVA version from 1.6 to 1.8, to fix you need to upgrade JAXB version from 1.x to 2.x.
