For google maps displayed using the maps component of JasperReports / JasperServer, you can use the text editor of your choice to change all occurances of http://maps.google.com/maps/api to https://maps-api-ssl.google.com/maps/api in the three files named maps.js, jasperreportsmap.js, and MapElementHtmlTemplate.vm that can be found in the folder path net/sf/jasperreports/components/map/resources in the main jasperreports jar file. That's the file in the WEB-INF/lib folder of JasperServer named something like jasperreports-5.5.0.jar. If you are using the default map marker icons on your map, you may still get a warning message in your browser about unencrypted elements such as images, because of the references in these same files to the marker icon files at the non-SSL url that begins with http://chart.apis.google.com . I'm not sure what the proper https location for those marker files should be - but if you figure it out, please post the proper URL here.
