java.util.ConcurrentModificationException - Axis 1 Webservices Extension

Description

We migrated some webservices from Coldfusion to Lucee and we sometimes face a error that some webservices throw java.util.ConcurrentModificationException.

Lucee: 5.3.9.160
Java: 11.0.16.1
OS: Ubuntu 20.04
Axis 1 Webservices: 1.4.0.37-SNAPSHOT

For me it look like its due a old org.apache.axis version.
Error thrown due org.apache.axis.description.JavaServiceDesc.getOperationsByQName(JavaServiceDesc.java:527)
which seem to be fixed in this commit: https://github.com/apache/axis-axis1-java/commit/d75ee4619c042ded4d3ee1f7b08e379f83572575

So it should be fixed, if we can update to a newer version. But im not sure if there will be a release available… Maybe we need to cherry-pick this.

Hi, can you explain what part you mean? And what is it replaced by?

Michael Offner 21 May 2024 at 20:00

this part of the project is deprecated and only get security fixes, sorry.

David Raschper 6 July 2023 at 12:57

Ah got it! 👍
But the problem is now that it uses axis-axis-1.4 and there does not seem to be an update available (https://mvnrepository.com/artifact/axis/axis ). Also https://mvnrepository.com/artifact/org.apache.axis/axis does not have a newer version.
Not really sure how to handle that, since https://github.com/apache/axis-axis1-java also have no release.

Currently the only way would to build axis with this fixes yourself and create a new repo for this. (Kinda what i did now).

As I undestand is upgrading to Axis2 not that easy, due its a complete rewrite and dont seem compatible. Will Axis only used for cfinvoke with webservice attribute and the cfc?wsdl ?
ACF seem to support both versions https://coldfusion.adobe.com/2017/10/axis-2-and-axis-1-compatibility-issues-in-coldfusion/ , not sure if they will do drop axis1.

the org axis bundle is found here https://github.com/lucee/osgi-bundle-axis it’s just some build scripts

After some more time spent, i was able to build the extension. slightly smiling face
I had to take the source from https://archive.apache.org/dist/ws/axis/1_4/ and than cherry picked the concurrency-fixes.

First i wanted to build the Axis-RT-Code https://github.com/apache/axis-axis1-java/tree/master/axis-rt-core , but it seem that there need to be more work done. When using that library in the axis extension, there are coming some noclassdeffounderror-exceptions and other errors.

If anyone else have problems with this bug, feel free to use the fixed extension.
I would like to create a pull-request or help with this issue, but i still dont understand where and how you build this library (org.lucee.axis-1.4.0.0006L.jar).

 

Library:https://github.com/Xcreen/axis
Extension: https://github.com/Xcreen/axis/releases/download/1.4.1/org.lucee.axis.extension-1.4.0.40-SNAPSHOT.lex
