ADDITIONAL OS VERSION INFORMATION :
Windows XP Pro SP2

EXTRA RELEVANT SYSTEM CONFIGURATION :
Idem if 1.5 is used.

A DESCRIPTION OF THE PROBLEM :
When the getMethod is called using 1.3.1 no error

But with 1.4.1 the following error occur :

java.lang.NoClassDefFoundError: sans_titre3_lib1/Sans_titre3
  at java.lang.Class.getDeclaredMethods0(Native Method)
  at java.lang.Class.privateGetDeclaredMethods(Class.java:1655)
  at java.lang.Class.getMethod0(Class.java:1901)
  at java.lang.Class.getMethod(Class.java:984)
  ...


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :

Create "lib3.jar" which contain class "Class3" (using 1.3 or 1.4)
 
Create "lib2.jar" which contain class "Class2" having method (using 1.3 or 1.4):
   * getString
   * getClass3
    

Creation application "Application" which:
   * create a ClassLoader containing "lib2.jar"
   * get Class Class2
   * call method "getMethod" for "getString" on Class2

Put lib2.jar into d:\temp folder

Build and execute application "Application" using 1.3 or 1.4:
 Error or no error !!!!


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Using 1.3.1 ==> No Error

Uding 1.4 ==> Error
java.lang.NoClassDefFoundError: lib3/Class3
  at java.lang.Class.getDeclaredMethods0(Native Method)
  at java.lang.Class.privateGetDeclaredMethods(Class.java:1655)
  at java.lang.Class.getMethod0(Class.java:1901)
  at java.lang.Class.getMethod(Class.java:984)
  at application.Application1.main(Application1.java:28)

 
    
ACTUAL -
No error with 1.3.1.


ERROR MESSAGES/STACK TRACES THAT OCCUR :
The error message is, using 1.4.1:
java.lang.NoClassDefFoundError: lib3/Class3
  at java.lang.Class.getDeclaredMethods0(Native Method)
  at java.lang.Class.privateGetDeclaredMethods(Class.java:1655)
  at java.lang.Class.getMethod0(Class.java:1901)
  at java.lang.Class.getMethod(Class.java:984)
  at application.Application1.main(Application1.java:28)


REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
No identify workaround except include lib3.jar into the URL but for our application, using a dynamic loader process, lib3.jar is unknown.

Release Regression From : 1.4.1
The above release value was the last known release where this
bug was known to work. Since then there has been a regression.
