Product Version = NetBeans IDE Dev (Build nbms-and-javadoc-7840-on-20110906)
Operating System = Windows 7 version 6.1 running on amd64
Java; VM; Vendor = 1.7.0
Runtime = Java HotSpot(TM) 64-Bit Server VM 21.0-b17

Example:

mytemplate.tpl:

{literal}
<script type="text/javascript">
function addMarker(id, image,location)
{

	var marker = new google.maps.Marker({
		position: location,
		map: map,
		icon: image,
		draggable: {/literal}{if $draggable}true{else}false{/if}{literal}
	});


	globalMarkers[id] = marker;

	return marker;
}
--more javascript below--
</script>

To reproduce, select the whole function. Press tab to indent it. This takes a bit longer than 'normal'. Press shift tab to remove the indent. Again this takes a bit long.
Now for the fun of it, copy paste the text "globalMarkers[id] = marker;" aprox. 30 times below it. Then do the shift indent again as before. Now it takes very long.

If you try to indent the whole file ~200 lines, Netbeans bails out with a java out of memory bug report window. 

Note, I wanted to report it thru the bug report popup window but while uploading the bug report (progress bar, bottom right), it again stopped telling me it was out of memory! (Uploading a file should not take many gb's of mem?).

Please contact me if you want to know more details (installed plugins?)
