Curly braces in ${bsh; ...}

[X Gylee]

I tried to use a Java method in a form widget:

<display description="${bsh: String.format(&quot;%,d&quot;, new Integer[]
{12345});}" />

However, OFBiz treated the first closing curly, which is the end of an array
initializer, as the end of the whole ${bsh: ... }, and this created an
incorrect output.
I have tried to replace the array curlies with &#x7b; and &#x7d;, but they
had no effects.
Is there a way to escape inner curlies?

I am using OFBiz from trunk rev 612332 (Jan 16, 2008).
