[Jessie-discuss] 1.4 support? ("1.4 not enabled")

[Martin Egholm Nielsen]

Hi there,

I'm trying to use Jessie as a replacement for Sun's implementation.
However, I reach a point where Sun's "java.net.Socket" invokes a method 
on Jessie's SSLSocket that is not supported (#isInputShutdown):

Exception in thread "main" java.lang.UnsupportedOperationException: 1.4 
methods not enabled
        at 
org.metastatic.jessie.provider.SSLSocket.isInputShutdown(SSLSocket.java)
        at java.net.Socket.getInputStream(Socket.java:701)
        at 
org.metastatic.jessie.provider.SSLSocket.setupIO(SSLSocket.java:1170)
        at 
org.metastatic.jessie.provider.SSLSocket.getOutputStream(SSLSocket.java:591)
        at test.Test1.main(Test1.java:73)

If I scan the source for Jessie's SSLSocket, I however see that there is 
some commented code in #isInputShutdown:

public boolean isInputShutdown()
  {
    //if (underlyingSocket != null)
    //  {
    //    return underlyingSocket.isInputShutdown();
    //  }
    //else
    //  {
    //    return super.isInputShutdown();
    //  }

    throw new UnsupportedOperationException("1.4 methods not enabled");
  }

that looks somewhat ok to me :-)

So, my question: Should one avoid using Jessie with Suns Java 1.4, and 
do you know whether the new GCJ 4.0 has been "designed" to avoid these 
1.4 methods?

BR,
