The licensee found some classes crash with stack overflow in 1.4.2b23
on Windows 2000.

Reproduce :
 1) unfold the attched crash.tar
  => you will see the "crash" dir. appear.
 2) Go to crash dir. and invoke "java -server TEST"
  => You will see the attached crash.jpg file.
  
Configration:
 MPU: Pentium 1.4 [GHz]
 Mem: 384 [MB]
 OS : Windows 2000 (SP2, Japanese)
 JRE: 1.4.2
 
 
NOTE:

1) Additional information fron the licnesee

 This issue does not occur on solaris box.
 The following Tabel shows their result on each platform.
  
                        Win2000 Solaris7
----------------------------------------------
jdk1.3.1_08 -server NG OK
             -hotspot OK OK
jdk1.4.1_02 -server NG OK
             -hotspot OK OK
jdk1.4.2_b23 -server NG OK
             -hotspot OK OK
----------------------------------------------
- "NG" means 'crash occurs", "OK" means "crash does not occur".
- They show the results on solaris box just for comparing with that
  on Windows.
  (Solaris box: sparc 600[Mhz] * 4CPU, 4.5[GB] Solaris7)


Besides, they sent stack traces with VC++ in each jre version.
They consider there seems some problems in c2 optimization
according to the traces.
