IllegalArgumentException: does not contain '='

[naoliv]

Using an incomplete (and thus wrong) validation rule:

*["addr:postcode" =~ /^[0-9]{8}$/] {
        throwWarning: tr("CEP pode ser melhorado");
        fixAdd: concat(substring(tag("addr:postcode"), 0, 4), "-", substring(tag("addr:postcode"), 5, 7));
}

I got this:

It's the same problem from #13630

[Don-vip]

In 12975/josm:

fix #13920 - robustness against invalid mapcss code - catch error and log it (fix command is optional)
