Hi,
I think I am experiencing a race condition that occurs in geoserver when
creating a layer group with a layer.
I am using geoserver 2.8.1.
I am using geoserver java libraries in the following way:
===
Workspace defaultWorkspace = ...;
if (null == defaultWorkspace)
{
// throw exception
}
// First define the coverage store and coverage:
CoverageStore coverageStore = new CoverageStore();
coverageStore.setName("Coverage_1");
coverageStore.setIsEnable(true);
coverageStore.setresourceURL(<path>);
coverageStore.setWorkspace(defaultWorkspace);
Coverage coverage = new Coverage();
coverage.setCoverageStore(coverageStore );
coverage.setIsEnabled(true);
coverage.setName("Coverage_1");
// Secondly, define the layer group
LayerGroup layerGroup = new LayerGroup();
layerGroup.setName("LayerGroup_1");
layerGroup.setLayers( new HasSet<Layer>());
layerGroup.getLayers().add(coverage);
// Send the REST request
=== end of the code
In geoserver log file, I can see cases where the layer group is created
fine, and some cases where the layer group is not created because the layer
creation is not complete.
*Case 1: layer group is created fine*

Is this a bug in geoserver? Is it some configuration mistake?
