Comment:

 Finally i got chance to spent time on this issue as earlier workaround did
 not work well with GWC & geoserver layergroup.

 Root cause of this issue in Openlayers wrapDateLine fix which not
 considered tolerance value for both sides.

 I modified the Layer.js (line 1292) code segment

         if (this.wrapDateLine) {
             // wrap around the date line, within the limits of rounding
 error
             var wrappingOptions = {
                 'rightTolerance':this.getResolution()
             };
             bounds = bounds.wrapDateLine(this.maxExtent, wrappingOptions);

         }

 As below:

         if (this.wrapDateLine) {
             // wrap around the date line, within the limits of rounding
 error
             var wrappingOptions = {
                 'rightTolerance':this.getResolution(),
                 'leftTolerance':this.getResolution()
             };
             bounds = bounds.wrapDateLine(this.maxExtent, wrappingOptions);

         }

 Then it works fine. Pls include this fix to next release as prefer to use
 realase version as it helps to get other fixes and new features.
