Javatemplates s:file shows server/file location

After a file upload with the s:file tag it gives details of the webapp location in the value attribute.

<s:file name="uploadedFiles" multiple="multiple" />

......value="/someplace/Tomcat/apache-tomcat-9.0.85/work/Catalina/localhost/ROOT##/upload_52c5bcff_6363_4414_b23e_fe49bb3f3af7_00000462.tmp" .....

If I look at file.ftl there is no value being set for the s:file tag, so the preset value has been removed. ie

<#if parameters.nameValue??>
value="<@s.property value="parameters.nameValue"/>"<#rt/>
</#if>

In the javatemplates plugin FileHandler.java it does set the value, and gets it from

addIfExists("value", params.get("nameValue"))

which has the server path details.

Possibly the file.flt was modified at some point, and the java templates version was not.

I guess we should make these match and remove the value on the javatemplates?
Update the docs also.
