Hi all,
I tried to run SableBOT on glue (sparc) and I hit some strange problem.
I just re-tried it at home and I get the same result. Things go well
with Sun's JDK.
$ java-sablevm SableBot
java.lang.ClassNotFoundException: java.lang.String;
at gnu.java.lang.SystemClassLoader.findClass
(SystemClassLoader.java:79)
at java.lang.ClassLoader.loadClass (ClassLoader.java:327)
at java.lang.ClassLoader.createArray (ClassLoader.java:369)
at java.lang.VirtualMachine.createArray (VirtualMachine.java:102)
at SbtConfig.getSA (SbtConfig.java:64)
at SbtIRC.readConfig (SbtIRC.java:55)
at SableBot.main (SableBot.java:35)
at java.lang.VirtualMachine.invokeMain (VirtualMachine.java)
at java.lang.VirtualMachine.main (VirtualMachine.java:88)
$ strace java-sablevm SableBot 2>&1 |grep ^open\(
open("sablebot.conf", O_RDONLY) = 6
open("/usr/share/sablevm/sablevm-classpath/java/io/BufferedReader.class", O_RDONLY) = 7
open("/usr/share/sablevm/sablevm-classpath/java/io/InputStreamReader.class", O_RDONLY) = 7
open("/usr/share/sablevm/sablevm-classpath/java/lang/Integer.class",
O_RDONLY) = 7
open("/usr/share/sablevm/sablevm-classpath/java/lang/Number.class",
O_RDONLY) = 7
open("/usr/share/sablevm/sablevm-classpath/java/lang/Long.class",
O_RDONLY) = 7
open("/usr/share/sablevm/sablevm-classpath/java/lang/String;.class",
O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/share/sablevm/sablevm-classpath/java/lang/Throwable$StaticData.class", O_RDONLY) = 7
I tried different jikes ver. to compile SableBOT and sablevm-classpath
but it didn't change the outcome. Looks like there's some glitch in
.class file parsing, because in the format you have semicolon after
class name.
To reproduce the problem do the following:
cd /tmp
wget http://gadek.debian.net/sablebot.tgz
tar zxvf ./sablebot.tgz
cd ./sablebot
sablevm -Y SableBot
The strange thing is that I haven't hit it with many different programs,
nor I've ever seen it before. Has anyone touched the .class parser?

Hello, I just run SableBOT from SableVM/staging. In case you don't know, the directory for logs need to be manually created, otherwise: FATAL: Error accessing log file /tmp/sablebot/web/logs/sablebot.log Then I get: Trying to connect to server: irc.sablevm.org port 6667 SableBOT started NOTICE AUTH :*** Looking up your hostname... 0>>>|NOTICE| 1>>>|| 2>>>|| 3>>>|AUTH| 4>>>|*** Looking up your hostname...| INTERPRETING: |NOTICE| getStrSpc dla |#sablevm| ret |#sablevm| len: 8 getStrSpc dla |#sablevm| ret |#sablevm| len: 8 getStrSpc dla |#sablecc| ret |#sablecc| len: 8 ... getStrSpc dla |#sablevm| ret |#sablevm| len: 8 getStrSpc dla |#sablevm| ret |#sablevm| len: 8 Broken pipe Do you still have the ClassNotFound?

Hi,
