hi ,barchart ,cause the oracle change the class InetSocketAddress's implement in the last release,so your native binding which get the filed id such as addr and port of the InetSocketAddress class will cause an error,not the change is moving the addr and port field to an inner class:

public class InetSocketAddress
    extends SocketAddress
{
    // Private implementation class pointed to by all public methods.
    private static class InetSocketAddressHolder {
        // The hostname of the Socket Address
        private String hostname;
        // The IP address of the Socket Address
        private InetAddress addr;
        // The port number of the Socket Address
        private int port;

        private InetSocketAddressHolder(String hostname, InetAddress addr, int port) {
            this.hostname = hostname;
            this.addr = addr;
            this.port = port;
        }
.....

    public InetSocketAddress(InetAddress addr, int port) {
        holder = new InetSocketAddressHolder(
                        null,
                        addr == null ? InetAddress.anyLocalAddress() : addr,
                        checkPort(port));
    }

.....

    private final transient InetSocketAddressHolder holder;

this change may be cause you guys to rewrite the native binding ...

1. is this the same change needed for android?
2. can you make the change and send pull request?

[He-Pin]

@carrot-garden
1 )This change only affect the oracle-java 6 and 7 last update and i am not that clear about the openJDK ,i think this may be the cause of the security issue just talk around on the web,the android don't need this adapt cause the android use the android style java API implement.

2. I noticed that you added the android support in your github projecct ,did you planing to support android now? When i porting your greate job to android platform,i counted the only issue is that [Issue ARM support for Android #18 ] ,and as you see ,i don't how how to change the native address convert to an android java's InetSocketAddress's instanse,this will cause the native crash when i call getSocketAddress,blablabla.

3. Could you guys write and roadmap on your wiki?So i will know what are you guys planning for.

4. i will trying to make this change ,should i check your source code from the maven repo but not the github?

Hello,

I've also encountered this problem in the little project that I take part in. It is 100% reproducible on Oracle's JRE 7u13 and 6u39.

[Thread-6] ERROR com.barchart.udt.SocketUDT - Failed to INIT native library
java.lang.NoSuchFieldError: port
at com.barchart.udt.SocketUDT.initClass0(Native Method)
at com.barchart.udt.SocketUDT.(SocketUDT.java:150)
at others.ReceiveFiles.setTransmisson(ReceiveFiles.java:273)
at others.ReceiveFiles.run(ReceiveFiles.java:365)

It is probably caused by fixing the http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-0433 vulnerability. The root cause was that method UDT_InitFieldRefAll access field 'port' in Java class InetSocketAddress (around line 400) that is private. Previous JREs allowed this, but in the newest one is the bug was fixed and thus the method doesn't work anymore. The fix would be to access the field value using public getter, and rewrite every function that sets this field's value that the new InetSocketAddress would be spawned with correct 'port' value (because there is no public setter for this field, it's accesible only through constructor).

[He-Pin]

@wmichal, yes you are right~!
the cause is the change just made by oracel in the InetSocketAddress implement.
Then should change the native implement of barchart-udt

[He-Pin]

@carrot-garden thanks,i will test it later.

try current snapshot

[CCob]

I can confirm this works with the latest JRE 7. Any chance you can cut a release (again, sorry).

[He-Pin]

@carrot-garden ,i confirm it works on the last oracle JDK 7 too,did it affect the older jre?

[He-Pin]

@CCob ,hi CCob,do you want to implement the android support?!

[CCob]

No I don't, do you :)

[carrot-garden]

released
https://oss.sonatype.org/content/groups/public/com/barchart/udt/barchart-udt-bundle/

[He-Pin]

@CCob ,i wanna to ,but i am going to my spring festival,when i go back hometwon ,i have no network connection...

[He-Pin]

@carrot-garden should the next version add support the older version of JDK or OpenJDK which not change the implement?

[carrot-garden]

this fix works fine both in old and new jdk
