When string object with the size of about 6 M-bytes is submitted, Applet is freezed with
such a "JVM heartbeat .. dead, send ts: 4300380568, now ts: 4310395675, dT 10015107"
message, or Applet is freezed with closing Java Console window.
- STEPS TO FOLLOW TO REPRODUCE THE PROBLEM:
OS: Windows XP SP2
Browser: IE6/IE7
JRE: 6u18
1. Make "test" directory and change the directory
2. Save the following codes
3. Compile the following java code (with -classpath "C:\Program Files\Java\jdk1.6.0_18\jre\lib\plugin.jar")
4. Create TestApplet.jar with test\TestApplet$1.class and test\TestApplet.class
5. Run the following HTML code
6. Input "6" as the data size in Applet
- EXPECTED VERSUS ACTUAL BEHAVIOR:
EXPECTED:
Such a "JVM heartbeat" message does not appear like JRE 6u17.
ACTUAL:
