Re: jdbc and nfs

No it hasn't anything to do with the classpath I've used...

I've investigated the problem a little bit further by profiling my
simple jdbc test class and found out that most of the time is spent in
this class:

sun.security.pkcs11.wrapper.PKCS11.C_Initialize

98% of the time is spent in that function with 3694 calls (well it
will last forever if I don't kill the process)!

So I guess it's a problem with Sun/Solaris security mixed with nfs issue...
