--------------------------------------
Summary: In the admin console the seiMethodHeaderParameter service
parameter should not be modifiable
Key: AXIS2-5716
URL: https://issues.apache.org/jira/browse/AXIS2-5716
Project: Axis2
Issue Type: Bug
Components: admin console
Affects Versions: 1.6.2
Reporter: Olivier Vanekem
In the admin console, some services are automatically tagged with the
seiMethodHeaderParameter service parameter.
This parameter takes an array as value instead of a String.
Because it appears in the parameters in the console, changing any other
parameter for the service will also send a value to this
seiMethodHeaderParameter parameter. This issue is that the admin console sends
all parameter values as String and therefore the seiMethodHeaderParameter now
contains a String value instead of an array.
This will result in an exception of the service at runtime with a
ClassCastException cannot cast a String into an array.
See such an exception below:

[ERROR] java.lang.String cannot be cast to java.util.ArrayList
java.lang.ClassCastException: java.lang.String cannot be cast to
java.util.ArrayList

Looking at the code of MustUnderstandUtils, we see indeed that it tries to
retrieve the value of the seiMethodHeaderParameter service parameter as in:
{code:java}
ArrayList seiMethodHeaders =
(ArrayList)axisService.getParameterValue("seiMethodHeaderParameter");
{code}
And this generates the exception because we changed (another) service parameter
but the admin console updated also seiMethodHeaderParameter with a string value.
