- is interpreted by the expression language as numerical subtraction.
e.g.
${foo- 12}
BTW you don't need to use <j:out>, its only there for JSTL support. So you
can do
<j:jelly xmlns:j="jelly:core">
<j:set var="repeat_count" value="5"/>
<j:set var="select_name" value="selectedLocale"/>
repeat count=${repeat_count}
select_name=${select_name}
</j:jelly>
