FULL PRODUCT VERSION :
java version "1.6.0_02"
Java(TM) SE Runtime Environment (build 1.6.0_02-b05)
Java HotSpot(TM) Client VM (build 1.6.0_02-b05, mixed mode, sharing)
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]
EXTRA RELEVANT SYSTEM CONFIGURATION :
Internet Explorer Version 6.0.2900.2180.xpsp_sp2_gdr.050301-1519CO, Update Versions: SP2
A DESCRIPTION OF THE PROBLEM :
I launch a page with one small, signed applet on it. This applet is a small web server to load other pages. When executed in Internet Explorer, IE crashes with a report from the plug-in on the desktop. The program crashes when attempting to call BufferedReader.readLine(). The crash is ultimately caused by SocketInputStream.socketRead0() at the top of the stack. This problem is new in 6.0u2; 6.0 and 1.5.0_11 work well.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Execute the given applet in IE.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
New IE window opens with served pages.
ACTUAL -
The IE window pops up, but immediately the IE process instantly ends with a crash report from the plug-in.
ERROR MESSAGES/STACK TRACES THAT OCCUR :
(see attachment: hs_err.log)
REPRODUCIBILITY :
This bug can be reproduced always.
