FreeBSD jdk15 does not read java.security?

[Zsolt Kúti]

Hi Nick,

Here is what I see on my system:

$ truss -o truss.out java Test    
freebsd.org/69.147.83.40Memory fault (core dumped)

The ending lines of truss.out:
..
open("/usr/local/diablo-jdk1.5.0/jre/lib/i386/libzip.so",O_RDONLY,00) =
4 (0x4) open("/usr/local/diablo-jdk1.5.0/jre/lib/rt.jar",O_RDONLY,00) =
4 (0x4) open("/usr/local/diablo-jdk1.5.0/jre/lib/jsse.jar",O_RDONLY,00)
= 4 (0x4)
open("/usr/local/diablo-jdk1.5.0/jre/lib/jce.jar",O_RDONLY,00) = 4
(0x4)
open("/usr/local/diablo-jdk1.5.0/jre/lib/charsets.jar",O_RDONLY,00) = 4
(0x4)
open("/usr/local/diablo-jdk1.5.0/jre/lib/i386/client/classes.jsa",O_RDONLY,00)
= 4 (0x4) open(".hotspot_compiler",O_RDONLY,0666)          ERR#2 'No
such file or directory'
open("",O_APPEND|O_SHLOCK|O_CREAT|O_EXCL|O_NOCTTY|O_DIRECT|0xbf7e1000,05002553414)
= 5 (0x5)

I do not know why that error after opening classes.jas as:
$ l /usr/local/diablo-jdk1.5.0/jre/lib/i386/client/classes.jsa
-r--r--r--  1 root  wheel  12689408 Feb 10
