I always do one of the following (in a JSR-223 Groovy script):
try {
1 / 0 // throw an exception
} catch(e) {
log.info("Ooops: " + e); // without stacktrace
log.info(Ooops: " + e, e); // with stacktrace
}
but if you are afraid of the Groovy methods in the stacktrace, you can use
log.info("OOOps: " + ,
org.codehaus.groovy.runtime.StackTraceUtils.sanitize(e))
The sanitize method works on the original excpetion (in this case e) and
gives back a new exception with a sanitized stacktrace.
