StringTemplate escape back slash not working as expected

Assume

owner=owner
name=name

I expect StringTemplate

<pre>$owner$ touch \\$name$</pre><br>

to generate

<pre>owner touch \name</pre><br>

But it's giving out an error

Can't parse chunk: </pre><br>

If I add a space between \\ and $, it works as expected.

<pre>$owner touch \\ $name</pre><br>

will generate

<pre>owner touch \ name</pre><br>

It appears that it interprets \\$ as escaping \$ instead of \\

StringTemplate java 3.2.1

Any idea how to write the correct StringTemplate? Is this a bug?
