Quick clicking causes deserialization error: ClassNotFoundException
-------------------------------------------------------------------
Key: WICKET-1813
URL: https://issues.apache.org/jira/browse/WICKET-1813
Project: Wicket
Issue Type: Bug
Affects Versions: 1.3.4
Reporter: Martijn Dashorst
First reported on the list, but sent off-line (why?) to me:
Thank you very much for the reply.
I am not sure if "ClassNotFoundException" is misleading. If really
"ClassNotFoundException", the same class should still not be found whether I
repeat the click slowly or rapidly. But it seems to me that this exception
appears only when I repeat the click rapidly enough.
The complete stack trace shown on the web page is as follows. I noted that they
mirrored what have been logged by Tomcat.
Tomcat version : 1.6.0.18
java version "1.6.0_07"
Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
Java HotSpot(TM) 64-Bit Server VM (build 10.0-b23, mixed mode)
Thank you very much again!
Wilfred
(I later assembled an application with Spring + Freemarker doing similar
demonstration on the same Tomcat. When I repeatedly clicked "add to cart", a
cheese item did go to the cart on each click without breakdown no matter how
quickly the repetition was.)
