[jcifs] Re: jcifs-1.1.9 ArrayIndexOutOfBoundsException: -2146866174

Hi Michael,
CIFS servers were Windows XP and Windows 2003.
OS where the test was carried out: Windows XP, Solaris, HP-UX PA-Risc 
and HP-UX True64. The problem turned up in all of them.

Attached you can find the exception and the T2Crawler. 

Coming back to my last question, I have been testing Jcifs under 
different plattforms and the error fixed in 1.1.9 only occurred in HP-
UX, I tried with 5 different HP-Ux machines and all of them had the 
problem. I tried with 3 windows, 2 linux (Fedora and Mandrake) and 2 
solaris and they didn´t have the problem of high load, even when the 
shares accessed and the code being tested were exactly the same. Do you 
know why the HP-UX machiens have "high-load" problems when  the other 
machines did not have the problem at all? Could this mean a JVM 
implementation problem in the HP plattform? It is even more weird if we 
take into account that the mandrake linux was running on a PIII 750Mhz 
box and was much faster that the HP-ux Machines. Jcifs running on HP-Ux 
machines required 3 times more(approx ) time than the Solaris, Linux 
and Windows machines to crawl the same CIFS share. All machines shared 
the same network and they were dedicated to the test, no other tasks 
were carried during the tests. Any ideas would be appreciated.

Thanks for the quick answer and for the great product.

Regards,

Michael
