I'm trying to perform some fuzz testing by sending requests to a server
with malformed URIs.

The following minimal code worked well on Jersey 2.3.1:

ClientBuilder.newClient()
    .target(UriBuilder.fromUri("http://localhost"))
    .path("test{}")
    .request();

We just updated to 2.11.0 and the same code produces the following error:

java.lang.IllegalStateException: Illegal character "}" at position 5 is not
allowed as a start of a name in a path template "test{}".
    at

I'm trying to understand if this is related to
https://java.net/jira/browse/JERSEY-2525
It certainly doesn't look fixed in this version.

Any ideas?

Thanks,
Gabriel
