FULL PRODUCT VERSION :
java version "1.6.0_03"
Java(TM) SE Runtime Environment (build 1.6.0_03-b05)
Java HotSpot(TM) Client VM (build 1.6.0_03-b05, mixed mode, sharing)

FULL OS VERSION :
Microsoft Windows XP Professional Version 2002 Service Pack 2

A DESCRIPTION OF THE PROBLEM :
Complie file Main.java including contents described later, which has only logics with a little complex inheritance, and run then crush VM with message EXCEPTION_ACCESS_VIOLATION.

Also I found that it is crushed by EXCEPTION_ACCESS_VIOLATION for Java 5.0 (jdk1.5.0_14) in the same Windows XP, and SIGSEGV for jdk1.5.0_10 in (uncertain) Linux OS.

It seems that adding or deleting odd number of dummy methods prevents the crush.

THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: Yes

THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Yes

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
javac Main.java
java Main
