FULL PRODUCT VERSION :
java version "1.4.0_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0_01-b03)
Java HotSpot(TM) Client VM (build 1.4.0_01-b03, mixed mode)
FULL OPERATING SYSTEM VERSION :
customer Windows 2000 [Version 5.00.2195]
ADDITIONAL OPERATING SYSTEMS : (only 2. Problem)
Windows 2000
Windows XP
A DESCRIPTION OF THE PROBLEM :
1. Problem:
if you use
g.drawPolyLine(x, y, 100);
and x and y are not initialized, you get the the
errormassage below..
I made the mistake in line 185
2. Problem:
the system crashes!
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.Problem:
description under "Description"
2.Problem:
remove line 185 compile the program, start it, enter a big
value in the a4 textfield (i.e. 10 000 000)!
the error also occurs when the program is implemented as
applet.
i uploaded it to http://www.diablo2web.de
EXPECTED VERSUS ACTUAL BEHAVIOR :
1.Problem
i expectet a nullPointerException
2.I expected no system-crash

CUSTOMER WORKAROUND :
1. Problem: don't make the mistake to forget initializing
an array :)
2. Problem: don't have a work around
(Review ID: 178406)
======================================================================
DESCRIPTION OF THE PROBLEM :
Was due to the system call
g.drawPolyline(xp,yp,len) where 'yp' was null instead of an int[];
goes away when yp is properly initialized.
