RFR: 8029354: URLPermission. throws llegalArgumentException: Invalid characters in hostname

[Michael McMahon]

Hi,

java.net.URLPermission does not currently take account of the "userinfo" 
component
in the authority of a URL. So, it does not accept URLs of the form 
"http://username@host/blah";

http://cr.openjdk.java.net/~michaelm/8029354/webrev.1/

which includes a small spec change to account for this. Userinfo needs 
to be case-sensitive
for comparison, hashCode() etc.

Thanks,
Michael
