Subject tomcat-4.1 & kaffe; IllegalArgumentException: Attribute must be readable or writable
Date Wed, 25 Jul 2007 07:24:33 GMT
I have a bog standard tomcat-4.1 & kaffe install on OpenBSD 4.0 i386.

dmesg head shows that the box has little memory, JAVA_OPTS tuned to
suit.

Getting this exception (no search engine hits) as below, then tomcat
bails out, any pointers? (I fiddled about in catalina.policy with
attributes, but no joy):

$ more catalina.out
