gdbserver hangs while debugging threads

[sascha dot jaeckle at ntb dot ch (Jaeckle Sascha)]

Hi.
I'm trying to use gdb on a x86 host and gdbserver on a powerpc-linux
target (MPC823).
gdb is from the latest CVS-Sources and configured with
--target=powerpc-linux.

My files look like this:

//Test.java
public class Test {	
	public static void main(String args[]){	
	
	TestThread tt[] = new TestThread[10];
	
		for (int i=0;i<10;i++){	
			tt[i] = new TestThread();
			tt[i].start();
		}	
	}
}

 >>TestThread
public class TestThread extends Thread {

	public void run(){
	   		System.out.println(this.getName()); 
	
	    	yield();
	}
}

host>
#powerpc-linux-gcj --static --save-temps --main=Test -o Test Test.java
TestThread.java

target>
#gdbserver localhost:2345 Test
Process Test created; pid = 31

host>
#powerpc-linux-gdb Test core

0x100d792c in __syscall_rt_sigsuspend () at cni.h:106
106         { _Jv_MonitorExit (obj); }

Did anybody have the same problem? What I'm doing wrong?
C and C++ Sources are working fine.

Thanks
