@DaanHoogland ,

I did not propose a fix because I need help for that.

Hey @DaanHoogland, do not forget this other part of the code that only escapes /, then adds the God of wildcards (.*), and passes for a domain to be moved.

I guess this has the potential of corrupting all resources of the domain being moved or affecting some other unrelated domain that happens to match the Regex.

But I am not qualified to propose a code fix in this case. I would like your help to assess this bug, too.

Dear @DaanHoogland , you are correct. This was my intention to point out that the issue is also present in another line and I was looking for collaboration because I barely read some of the Java code I see.

Matcher matcher = pattern.matcher(newPathOfDomainToBeMoved);
if (!matcher.matches()) {
domainsOfResourcesInaccessibleToNewParentDomain.put(domainWithResourceUsedByDomainToBeMoved, entry.getValue());
