FULL PRODUCT VERSION :
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)

FULL OS VERSION :
Microsoft Windows XP version 5.1.2600

A DESCRIPTION OF THE PROBLEM :
J2SE 1.4.2's javac will not compile classes that have doubly-nested inner subclasses, such as the following test case:

class InnerClassBugTestCase
{
    private class InnerSuperclass extends InnerClassBugTestCase
    {
    }

    private class InnerSubclass extends InnerSuperclass
    {
    }
}

The error message provided is:

InnerClassBugTestCase.java:7: cannot reference this before supertype constructor has been called
    private class InnerSubclass extends InnerSuperclass

J2SE 1.4.2-beta and J2SE 1.4.1_03's version of javac compiles the class without errors or warnings.

REGRESSION. Last worked in version mantis-beta

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a text containing the following Java code:

class InnerClassBugTestCase
{
    private class InnerSuperclass extends InnerClassBugTestCase
    {
    }

    private class InnerSubclass extends InnerSuperclass
    {
    }
}

Save the file as InnerClassBugTestCase.java.

Attempt to compile InnerClassBugTestCase.java using J2SE 1.4.2's javac compiler: javac InnerClassBugTestCase.java

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
javac would compile the class into InnerClassBugTestCase.class.
ACTUAL -
javac did not compile the class, providing an error message that does not seem to apply.



ERROR MESSAGES/STACK TRACES THAT OCCUR :
InnerClassBugTestCase.java:7: cannot reference this before supertype constructor has been called
    private class InnerSubclass extends InnerSuperclass

REPRODUCIBILITY :
This bug can be reproduced always.
