Summary: Exception thrown while processing JS regular expressions

Initial Comment:
HtmlUnit failed load this reduced GWT test case.

<html>
<head>
<script language='javascript'>
function $replace(this$static, from, to) {
var regex, replacement;
regex = $replaceAll(from, "([/\\\\\\.\\*\\+\\?\\|\$\$\\[\\]\\{\\}$^])", "\\\\$1");
replacement = $replaceAll($replaceAll(to, "\\\\", "\\\\\\\\"), "\\$", "\\\\$");
return $replaceAll(this$static, regex, replacement);
}

function $replaceAll(this$static, regex, replace) {
replace = __translateReplaceString(replace);
return this$static.replace(RegExp(regex, "g"), replace);
}

function $substring(this$static, beginIndex) {
return this$static.substr(beginIndex, this$static.length - beginIndex);
}

function __translateReplaceString(replaceStr) {
var pos;
pos = 0;
while (0 <= (pos = replaceStr.indexOf("\\", pos))) {
replaceStr.charCodeAt(pos + 1) == 36 ? (replaceStr = replaceStr.substr(0, pos - 0) + "$" + $substring(replaceStr, ++pos)) : (replaceStr = replaceStr.substr(0, pos - 0) + $substring(replaceStr, ++pos));
}
return replaceStr;
}

function test() {
alert($replace("foobar", "foo", "$0"));
}
</script> </head>
<body onload="javascript:test()">

Message:
A reduced GWT test case is surely better than a full GWT test case, but
what about reducing it just to:
'$0'.replace(/\$/g, '\\$')

Now fixed in SVN.
