A DESCRIPTION OF THE PROBLEM :
When creating a java.net.URI object with a host that does not conform to the RFC, an exception is not thrown but many sections of the URI are not parsed to fields in the URI object. This leaves the URI in an inconsistent state without informing the caller of any issues.

If the URI is deemed to be invalid, an exception should be thrown (as documented), otherwise the URI object should be completely filled out.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a new java.net.URI object with a URI containing an invalid character in the hostname:

java.net.URI uri = new java.net.URI("http://my_host.com:1234")

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Either a URISyntaxException should be thrown, or the URI should be created with all fields populated
ACTUAL -
No exception is thrown, but uri.getHost() returns null and uri.getPort() returns -1

---------- BEGIN SOURCE ----------
//If URI will be considered valid
@Test
void uriTestConsisderedValid() {
  URI uri = URI.create("http://my_host.com:1234");
  assertEquals("http", uri.getScheme());
  assertEquals("my_host", uri.getHost());
  assertEquals(1234, uri.getPort());
}
//If URI will be considered invalid
@Test
void uriTestConsideredInvalid() {
  assertThrows(IllegalArgumentException.class, () -> URI.create("http://my_host.com:1234"));
}
---------- END SOURCE ----------
