When you extract last heapdump with gzip -dc < heapdump-694731.hprof.gz > result.hprof

you can see that 
org.netbeans.modules.editor.hints.ParseErrorAnnotation#77

has some Annotations with 88mb String descriptions like :

Expected semicolon ; after "/*Debitore delete - precontrolli
                jQuery("#debitore_delete").click(function() {
                    var id = jQuery("#jqlist_debitori").jqGrid('getGridParam', 'selrow');
                    if (id) {
                        var ret = jQuery("#jqlist_debitori").jqGrid('getRowData', id);
                        Debitori_exe('DELETE', ret.anagrafiche_id, ret.qualifica);
                    } else {
                        alert("Seleziona un Debitore");
                    }

Comment 4 Petr Pisl 2015-03-24 14:32:46 UTC 
I have went through more then 20 head dumps and all was cased by very big Error token in js file. 

The problem was that the js parser has better recovery then the coloring lexer. The hints are counted based on the ast. But the hints usually displays the text from the token which is on the error position. So if there were many hints in the long error token, then the text of error token was copied for every hint.

After the fix are not created some hints that has are position in the lexical error token.
