The '$' character no more allowed in java identifier since JDK 1.4.2 ?

Question

Since JDK 1.4.2, I'm no more able to compile java
sources. :-((
Their compilation worked fine on 1.3 and 1.4.1.
Note that these java sources are generated automatcally
via a tool.
<b>The $ (dollar) character seems to be no more allowed
in java identifier.</b>
Here is a part of the Java Language Specification (second edition):
"An identifier is an unlimited-length sequence of Java letters and Java digits, the first of which must be a Java letter.
An identifier cannot have the same spelling (Unicode character sequence) as a keyword (�3.9), boolean literal (�3.10.3), or the null literal (�3.10.7).
A "Java letter" is a character for which the method
Character.isJavaIdentifierStart returns true.
A "Java letter-or-digit" is a character for which the method Character.isJavaIdentifierPart returns true.
The Java letters include uppercase and lowercase ASCII Latin letters A-Z (\u0041-\u005a), and a-z (\u0061-\u007a), and, for historical reasons, the ASCII underscore (_, or \u005f) and dollar sign ($, or \u0024). The $ character should be used only in
mechanically generated source code or, rarely, to access preexisting names on legacy systems.
Here is the result of the Character methods on JDK 1.4.2:
<code>
Character.isJavaIdentifierPart('$'): true
Character.isJavaIdentifierStart('$'): true
</code>
Here are two very samples java sources which reproduce
this probleme
<code>
package sb;
public interface Essai {
public void method1(int i);
public static class InnerClass {
public void test() {};
public void setInnerClass(InnerClass ic);
package sb;
public class EssaiImpl implements Essai {
public void method1(int p1) {
public void setInnerClass(sb.Essai$InnerClass p1) {
</code>

Answer 1

public void setInnerClass(sb.Essai$InnerClass p1) {There is no type named Essai$InnerClass defined anywhere in your program. That is an error in your program that previous compilers failed to detect.
