Bug#512473: gcj-4.3: Uses StringBuilder in 1.4 mode

["Adrian Lang" <debian@adrianlang.de>]

Package: gcj-4.3
Version: 4.3.2-2
Severity: normal

Consider the following class:
----
public class Testclass {
    public void testfunc() {
        int i = 5;
        new String("i is " + i);
    }
}
----

now compile with
----
gcj -fsource=1.4 -C Testclass.java
----

----
$ grep StringBuilder *
Binary file Testclass.class matches
----

As you may see, java.lang.StringBuilder is used in this classfile.
However, Java 2 Platform SE v1.4 has no such class.
(http://java.sun.com/j2se/1.4.2/docs/api/java/lang/package-summary.html)

A class compiled for 1.4 should use java.lang.StringBuffer instead.
