[xwiki-users] How to sort hashmap with velocity?

Hello, with velocity I have a hashmap: sort of variable with (key:value) that I want to sort, then I use: #set ($myHashMap = $collectionstool.getSortedMap(String, String)) $myHashMap.put('Mykey3','My value 3') http://platform.xwiki.org/xwiki/bin/view/ScriptingDocumentation/?url=http:%… It's working well ... except with uppercase because I want a sort with insensitive case. I tried to decrypt Javadoc and I found I could use: String.CASE_INSENSITIVE_ORDER #set ($myHashMap = $collectionstool.getSortedMap(String.CASE_INSENSITIVE_ORDER, String)) #set ($myHashMap = $collectionstool.getSortedMap(String::compareToIgnoreCase, String)) with java8 but unfortunaly it doesn't work (I have xwiki error) Any idea to sort my hashmap with with insensitive case? (Unfortunaly the better way I found is an ugly way: I mix velocity with a piece of groovy but I'm not satisfied at all because I use velocity loop and other if.) Thxs for any help. Pascal B
