Yes. On ppc "gcj -C stringconst2.java" gives me:
 0: ldc #13=<String "stringconst2">
 2: invokestatic #19=<Method java.lang.Class.forName 
(java.lang.String)java.lang.Class>
 5: astore_1
 6: aload_1
 7: ldc #20=<String "q">
 9: invokevirtual #24=<Method java.lang.Class.getField 
(java.lang.String)java.lang.reflect.Field>
 12: astore_2
 13: getstatic #30=<Field java.lang.System.out java.io.PrintStream>
 16: aload_2
 17: aconst_null
 18: invokevirtual #36=<Method java.lang.reflect.Field.get 
(java.lang.Object)java.lang.Object>
 21: invokevirtual #42=<Method java.io.PrintStream.println 
(java.lang.Object)void>
 24: goto 28
 27: astore_1
 28: return
