Error executing page compilation Circular extends reference for class Sample.deadlock

[talha06]

Hi everyone,

I'm trying to compile my Ext JS 4.1.1.a based application using 64-bit Linux OS.
Here's my application hierarchy(Maven based Java Web Application):

+ src
    +main
       +webapp
          + extjs
          + app
          - app.js
          - index.jsp
           + resources
           + WEB-INF

It's a huge project, so I'd like to learn how can I find the classes that generates error. Here is the error stacktrace:

[ERROR]        Circular extends reference :
Sample.deadlock.A ->
Sample.deadlock.B ->
Sample.deadlock.E ->
Sample.deadlock.C ->
Sample.deadlock.D ->
Sample.deadlock.A
[ERROR]        Error executing page compilation Circular extends reference for class Sample.deadlock.A
[ERROR]        com.sencha.exceptions.ExCircularReference: Circular extends reference for class Sample.deadlock.A

Thanks in advance.
