When trying to construct an LdapURL object with a bad input string (in this example the _ in ad_jbs is causing issues), and not using
the backward compatibility flag -Dcom.sun.jndi.ldapURLParsing="legacy" we run into the exception below :

import com.sun.jndi.ldap.LdapURL;
 ....
String url = "ldap://ad_jbs.ttt.net:389/xyz"; // bad input string containing _
LdapURL ldapUrl = new LdapURL(url);


java --add-opens java.naming/com.sun.jndi.ldap=ALL-UNNAMED LdapParseUrlTest
Exception in thread "main" javax.naming.NamingException: Cannot parse url: ldap://ad_jbs.ttt.net:389/xyz [Root exception is java.net.MalformedURLException: unsupported authority: ad_jbs.ttt.net:389]
at java.naming/com.sun.jndi.ldap.LdapURL.<init>(LdapURL.java:115)

Caused by: java.net.MalformedURLException: unsupported authority: ad_jbs.ttt.net:389

I would like to add the host and port info to the exception (in the example it is host:port of URI:null:-1] ) so that it is directly visible that the input caused the construction of a URI
with "special"/problematic host and port values.
