Java.net.Proxy supports socks5, is there a way to support socks4 as well? third party library is ok too.
Best Answer
java.net.Proxy SHOULD support SOCKSv4 but doesn't in either OpenJDK6 or OpenJDK7. I am planning to file a bug.
But the SOCKSv4 code is already there and can be turned on.
Use reflection to pull out the impl field in a java.net.Socket object. Cast that object to java.net.SocksSocketImpl. Use reflection to set the useV4 boolean field in this object to true.
According to the man sockd.conf, by default, it supports both of v4 and v5. But you can specify only v4 by using proxyprotocol option, something like this:
route {
from: 0.0.0.0/0 to: 0.0.0.0/0 via: 127.0.0.1 port = 1080
protocol: tcp
proxyprotocol: socks_v4
command: connect
method: none
}
The Java heap is a block of memory that holds java objects.
"pmap" shows the Operating System process heap. This is the memory used to run the java process. This includes all the java code, plus all the C code that makes up the java run time environment.
To show the java heap try Memory tab of jconsole, or jmap or jstat.

Then connect and it should use SOCKSv4.
