FYI:

  This bug will lead to failures of the following tests on machines with hostname starting from digits.
    - test/jdk/sun/tools/jstatd/TestJstatdExternalRegistry.java
    - test/jdk/sun/tools/jstatd/TestJstatdPort.java
    - test/jdk/sun/tools/jstatd/TestJstatdPortAndServer.java
    - test/jdk/sun/tools/jstatd/TestJstatdRmiPort.java

So it's worth fixing it.

Testing:
  - tier1-3 on Linux/x64

Thanks.
Best regards,
Jie

Hi all,

JBS:    https://bugs.openjdk.java.net/browse/JDK-8251155
Webrev: http://cr.openjdk.java.net/~jiefu/8251155/webrev.00/

HostIdentifier fails to canonicalize hostname:port if the hostname starts with digits.
The current implementation will get "scheme = hostname".
But the scheme should not be started with digits, which leads to this bug.

Thanks a lot.
Best regards,
Jie
