I've tried your workaround, but it doesn't work. This is the error message from the log:
{code}
Cannot resolve expression 'regex('^/path/([^/]+)/(.*)/?$') -> rewrite('/newpath'); set(attribute='%{QUERY_STRING}', value='param1=${1}&param2=${2}'); done()' 
{code}

I guess it won't be sufficient to add the quotation mark as end token. Imagine a rewrite rule where one wants to compose a single value from two capture groups:
request: http://myhost.com/path/a/b/c
rewritten to: http://myhost/path?resource=a-b-c.xml
the rule would be: (... regex omitted.. ) -> rewrite ('/path'): set(attribute='%{QUERY_STRING}', value='resource=$1-$2-$3.xml'). 
I think you should try to get the curly braces to work.

>             Project: WildFly
>          Issue Type: Bug

>    Affects Versions: 10.1.0.Final
>         Environment: * Windows 10
> * Wildfly 10.1.0 Final
> * Undertow Subsystem 1.4.13

> Context:
> A URL in the form of "http://somehost.org/path/a/b" should be rewritten to "http://somehost.org/newpath?param1=a&param2=b"
> The following filter should perform this rewrite:
> {code}
> <expression-filter name="rewrite-path" expression="regex('^/path/([^/]+)/(.*)/?$') -> rewrite('/newpath'); set(attribute='%{QUERY_STRING}', value='param1=$1&amp;param2=$2'); done()"/>
> {code}
> Problem:
> The output is (according to access-log);
> {code}
> somehost.org "GET /newpath?param1=b 
> {code}
> * param1 is assigned to the value of $2
> * param2 is dropped completly
