csupi updated CXF-4559:
-----------------------
Component/s: (was: JAX-WS Runtime)
> Part of SoapMessage content interchange between two concurrent webservice
> calls
> -------------------------------------------------------------------------------
>
> Key: CXF-4559
> URL: https://issues.apache.org/jira/browse/CXF-4559
> Project: CXF
> Issue Type: Bug
> Affects Versions: 2.5.4, 2.5.5, 2.5.6
> Environment: Java 64-Bit Server 1.6.0_31
> Ubuntu 12.04 64-Bit
> Reporter: csupi
> Priority: Critical
>
> I have a simple cxf webservice call with a DTO parameter. There is a HashMap
> and some other fields in the DTO.
> I realized that there are some cases where the content in the map is changed
> somewhere on the server side.
> I created a simple unit test. I put a String into the map and into a field
> where the map is. Create a webservice with jetty and create 15 clients to
> call my webservice 1000 times.
> After the test execution I realized that about in the 2% of the calls, the
> String in the map differs from the value in the field.
> Here is my unit test:
