crypto problem

[Maxime Colas des Francs]

hello,

I attempt to use openpgp in my web application
For that i use an external provider.
I put jar files in WEB-INF/lib and in a 'load-on-startup' servlet, i call 
Security.addProvider() and i read a public key from a file for futur 
encryptions.

I start tomcat manually (with startup.sh) and it works, i encrypt

but my problem is :
when application restart "not manually", by class modified or by manager 
application stop & start request,
my 'load-on-startup' servlet is re-executed, and freeze when public key is 
reading ...
and in my catalina.out i find this :
