Name: gm110360 Date: 05/25/2004
FULL PRODUCT VERSION :
java version "1.4.2_03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_03-b02)
Java HotSpot(TM) Client VM (build 1.4.2_03-b02, mixed mode)
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]
EXTRA RELEVANT SYSTEM CONFIGURATION :
IE 6.0.2800.1106.xpsp2.030422-1633
A DESCRIPTION OF THE PROBLEM :
Plugin does not refresh applet in JAR during Internet Explorer Refresh.
Please note that is the raw class file is placed onto the server and the archive tag is NOT used, that everything works. The problem happens when JAR files are used for the applet.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) Place index.html onto server
2) Compile 'first' and place code.jar onto server
3) View index.html in IE using plugin 1.4.2, do not exit IE
3) Compile 'second' and overwrite code.jar on server
4) Press CTRL-Refresh in IE web browser
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
BBBBBBBBBB (second) should appear in the applet, because pressing refresh should obtain the new JAR from the server.
ACTUAL -
AAAAAAAAAA (first) appeared in the applet, meaning that although there is updated code (second) on the server, the Java plugin is still using the locally cached (first) code.jar
Reviewing the web server log files clearly shows a GET on index.html, but there is NO request at all for code.jar, even through CTRL-Refresh is pressed over and over in IE.
REPRODUCIBILITY :
This bug can be reproduced always.
