RenderedImageMapOutputFormat.readBestCoverage is improperly setting readParams
------------------------------------------------------------------------------
Key: GEOS-4311
URL: http://jira.codehaus.org/browse/GEOS-4311
Project: GeoServer
Issue Type: Bug
Affects Versions: 2.1-RC1
Reporter: Daniele Romagnoli
Assignee: Daniele Romagnoli
Fix For: 2.1-RC2, 2.1.x
Attachments: wmsPatch_21x.patch, wmsPatch_trunk.patch
The readBestCoverage method is improperly setting the readParams for the
incoming read operation, when it checks for interpolation and gridGeometry
parameters.
Look at this part of code:
final int size = length + (!foundGG && !foundInterpolation ? 2:1);
GeneralParameterValue[] readParams2 = new GeneralParameterValue[length +
size];
System.arraycopy(readParams, 0, readParams2, 0, length);
As you can see it is creating a GeneralParameterValue array with (length+size)
elements whilst the "size" variable has already been computed by adding some
elements to "length".
This results in having a too long array with several null parameters.
Using that simple line will fix it:
GeneralParameterValue[] readParams2 = new GeneralParameterValue[size];
