java.net.BindException doesn't include host info even when jdk.includeInExceptions is set to hostInfo

[Jaikiran Pai]

The security.properties file in Java 11 (and later) have a new
configuration:

# The categories are:
#
#  hostInfo - IOExceptions thrown by java.net.Socket and the socket
types in the
#             java.nio.channels package will contain enhanced exception
#             message information
#
# The property setting in this file can be overridden by a system
property of
# the same name, with the same syntax and possible values.
#
#jdk.includeInExceptions=hostInfo

As noted for that property, if hostInfo is set as a value for this
jdk.includeInExceptions then IOException thrown by java.net.Socket will
container additional information. Is this expected to work for all kinds
of connection issues related to Socket types? For example, I have a Java
program which creates a ServerSocket and (intentionally) binds it to
port which is already in use. I (as expected) keep seeing this exception:


Exception in thread "main" java.net.BindException: Address already in
use (Bind failed)
    at java.base/java.net.PlainSocketImpl.socketBind(Native Method)
    at
java.base/java.net.AbstractPlainSocketImpl.bind(AbstractPlainSocketImpl.java:436)
    at java.base/java.net.ServerSocket.bind(ServerSocket.java:381)
    at java.base/java.net.ServerSocket.bind(ServerSocket.java:335)
    at Bind.main(Bind.java:7)


However, even after setting the jdk.includeInExceptions=hostInfo, I
haven't been able to generate the host name and port against which this
BindException occurs. Is this part of the code, in the JDK, expected to
include this additional info for this exception?

P.S: Tried with both Java 11 and Java 14.
