Simpler and more efficient solution: use Class.getField.

public static int getIntForConstant(String constant) throws RuntimeException {
  try {
    Class c = GLEnum.class;
    java.lang.reflect.Field f = c.getField(constant);
    return f.getInt(c);
  } catch (NoSuchFieldException e) {
    throw new RuntimeException("Field " + constant + " not found");
  }
}

NoSuchFieldException is a checked exception and its conversion into a
RuntimeException makes it easier to write code around it without allowing
silent failures like returning -1 would.
