Hey,
A customer report today a very strange tomcat crash to me and
I can simulate this bugs with following releases and OS's:
Tested with Suse 9.3, Tomcat 5.5.12 /Apr 1.2.2 / openssl 0.9.8, jdk 1.5.0_03
Also tested with current SVN Head and fresh build tcnative from head
and Tomcat 5.5.12 / Maldens tcnative 1.1.0 dll / Windows XP
Start Tomcat with APR Http Connector and JSR 160 JMX Adaptor
request some pages via http Connector
start jconsole / open Mbeans tab
Open RequestProcessor tree
Open one off the RequestInfo MBeans
Result: -- jvm crashed --
Tomcat 5.5.12 ---
