Description
FULL PRODUCT VERSION :
java version "1.6.0_23"
OpenJDK Runtime Environment (IcedTea6 1.11pre) (6b23~pre11-0ubuntu1.11.10.2)
OpenJDK Client VM (build 20.0-b11, mixed mode, sharing)
ADDITIONAL OS VERSION INFORMATION :
Linux ubuntu 3.0.0-16-generic #28-Ubuntu SMP Fri Jan 27 17:50:54 UTC 2012 i686 i686 i386 GNU/Linux
A DESCRIPTION OF THE PROBLEM :
In javascript, if a string is less than 4 characters long, garbage characters will be appended to it when returned to Java.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Open the attached html file in Chrome or Firefox.
A Java applet will call several javascript functions and display return values in a table (both string value and hex-character dump)
The problem can be reproduced using
Chrome 17.0.963.56
or
Firefox 10.0.2
Precompiled java applet and html code is available on this url:
http://gs1.flyordie.com/linux-chrome-test/a.html
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Values ["", "1", "12","123", "1234", "12345", null] should appear in the first column of the table.
ACTUAL -
Instead of "", "1", "12" and "123" values with garbage characters appended will be displayed. Hex-dump shows character values fffd 62 53 fffd (or similar).
REPRODUCIBILITY :
This bug can be reproduced always.
