With a simple HelloWorld class:
$ cat HelloWorld.java
public class HelloWorld
{
 public static void main(String[] args) { System.out.println("Hello World!"); }
}
current HEAD works fine for me:
$ /home/andrew/build/gcj/bin/gcj --main=HelloWorld -O HelloWorld.java
$ LD_LIBRARY_PATH=/home/andrew/build/gcj/lib64 ./a.out
Hello World!
$ /home/andrew/build/gcj/bin/gcj --version
gcj (GCC) 4.6.0 20100928 (experimental) [trunk revision 164689]
Can you attach the testme.java file?
