Clearly something funky is going on. The *.jar should have been expanded to the actual jars. With the recent changes you should have gotten no C;C: mixup, and spaces in the path shouldn't matter (that was more for my benefit, as your not having any). If you are ok with it, I can get your email address and contact you directly. Don't want to post mine or yours here (spammers are watching ;-).

I don't know whether this ever worked properly. This seems to be an issue with spaces in the Path, but also with cygpath conversion. Can you please comment out the entire CYGWIN case statement in the cassandra script. Then add this into the cassandar.in.sh after the initial two initializations of these variables: CASSANDRA_SEP=':' case "<code>uname</code>" in CYGWIN*) CASSANDRA_HOME=<code>cygpath -s -m "$CASSANDRA_HOME"</code> CASSANDRA_CONF=<code>cygpath -s -m "$CASSANDRA_CONF"</code> CASSANDRA_SEP=';' ;; esac Finally, change the CLASSPATH setting variable in the for loop at the bottom to: CLASSPATH="$CLASSPATH$CASSANDRA_SEP$jar" Let me know if this is too complicated and I can see about getting you the raw scripts.

I was hoping for the CLASSPATH from the shell bash script right before the cygwin conversion (mostly to see if there is anything funky in there that may throw off cygpath). I agree, the extra C; components are strange and likely part of the problem. Please also put an echo $include in front of the . "$include" statement in the cassandra script. I am curious which config file is read (it should be ./cassandra.in.sh. That is where the CLASSPATH is composed, so it seems like there is something strange going on in there.

If you would be so kind to print the CLASSPATH before the cygpath conversion as well. The resulting CLASSPATH can not be -u, as the jvm is not aware of cygwin's special style of doing paths. And yes, the C; in there would indicate an issue in the path conversion. You could use -m instead of -w, which will cause windows style but with forward slashes (more cygwin friendly that way). Sorry, I don't have a valid cygwin setup handy right now to try (but if you get me the original CLASSPATH, we may see why you end up with the C;).

In whatever script you use, see about adding an echo of the CLASSPATH right before the jvm gets actually started.
