Hi [~veithen],
Currently I'm facing this issue. In our project we are using axis 1.4 and
migrating from old code to spring boot. In maven repo, 1.4.1 is being listed as
axis 2.
( <groupId>org.apache.axis2</groupId>
<artifactId>axis2</artifactId>
<version>1.4.1</version> ).
We are using axis plugin to generate wsdl files. So we don't really want to
change much. Isn't going from axis to axis2 a big change? Please kindly guide
me on this.

> Key: AXIS-2909
> URL: https://issues.apache.org/jira/browse/AXIS-2909
> Project: Axis
> Issue Type: Bug
> Components: Serialization/Deserialization
> Affects Versions: 1.4
> Environment: java full version "1.8.0_20-b26"
> Reporter: Kim Albertsson
> Assignee: Andreas Veithen
> Priority: Critical
> Fix For: 1.4.1
>
> Attachments: axis-concurrent-mod.stack-trace, diff.txt
>
> Original Estimate: 0h
> Remaining Estimate: 0h
>
> Java 8u20 introduced a change in how Collections.sort is implemented. See
> http://bugs.java.com/view_bug.do?bug_id=8032636 and
> http://bugs.java.com/view_bug.do?bug_id=8030848.
> The sorting is now deferred to the specific list implementation which can
> operate directly on the underlying data structure without making a defensive
> copy beforehand. This can cause a java.util.ConcurrentModificationException
> to occur.
> The error can be reproduced by compiling axis-1.4.1-SNAPSHOT using java
> 1.8.0_20 or later and running the maven test suite (mvn test). The error does
> not manifest every single run, but I have never had to run the tests more
> than 3 times to reproduce. The test that fails is
> test.concurrency.TestApplicationScope.
> The issue originates in
> org.apache.axis.description.JavaServiceDesc.getOperationsByQName where an
> unsynchronized call to Collections.sort is made. Synchronizing over the
> sorted array resolves the issue.
> A working patch that has been tested in the test suite is appended in
> diff.txt.
> The stack trace from the axis test-suite is appended below. Do note however
> that this stack trace does not show the actual error (The original error is
> caught and rethrown). To get the stack trace where the Collections.sort call
> is made you can run the specific test and attach the jdb configured to catch
> all java.util.ConcurrentModificationExceptions.
> The stack trace from my jdb session is appended as
> axis-concurrent-mod.stack-trace. It was generated from an apache tomcat
> instance running a webservice relying on axis.
