This is reduced from the eclipse problem I was seeing.
Compile the following Test.java with gcj --main=Test Test.java

public abstract class Test
{
  public static void main(String[] args) throws Exception
  {
    Class c = Class.forName("Invoke");
    Object o = c.newInstance();
    Test t = (Test) o;
    t.test("FALSE", false);
    t.test("TRUE", true);
  }

  public abstract boolean test(String s, boolean b);
}

Compile the Invoke.java class with gcj -C:

public class Invoke extends Test
{
  public boolean test(String s, boolean b)
  {
    if (b)
      System.out.println(s + ": TRUE!");
    else
      System.out.println(s + ": FALSE!");
    return b;
  }
}

Then run the expected output is:

FALSE: FALSE!
TRUE: TRUE!

But when running ./a.out you will get:

FALSE: TRUE!
TRUE: TRUE!

Running this completely interpreted (gcj -C Test.java; gij Test) produces the
correct output. It also works correctly on powerpc-unknown-linux-gnu (either
partly pre-compiled or fully interpreted).
