No, I have to attach "insecurely" no matter what. What happens to me is *after* falling back to an insecure connection. I gave up using jconsole after a while and used VisualVM exclusively to track-down the cause because it would give me better information (would connect with a mild error, JMX didn't work). I was able to reproduce it with the small test case I attached to the BZ issue. > I guess they somehow broke/tightened AttachAPI? > > Removing "-Djava.io.tmpdir" from catalina.bat does not help. I'll see if I can get a Windows VM running to try another environment. It's entirely possible this is a Mac / Oracle VM thing. > 2014-03-10 20:52 GMT+04:00 Christopher Schultz > <ch...@christopherschultz.net>: >> >> I stopped Tomcat, completely removed my web application, >> restarted Tomcat and I can connect without a problem. >> >> AFAIK, my application isn't doing anything with JMX. >> > > What is the state of Tomcat when you "completely removed my web > application"?

There were no web applications deployed at all.

The only imports of javax.* are those of Servlet > API. I wouldn't have expected that they would. The only thing I could think of was that maybe there was some kind of non-serializable object that the remote client (jconsole) was attempting to access that for some reason caused the whole thing to die. I would have expected a nicer error... not something like "can't connect using Attach API" and having both jconsole and YourKit fail utterly and VisualVM connecting yet without JMX support. > I wonder whether your issue is reproducible with Java 8 release > candidates, that some Oracle people were advertising on dev > mailing list. I could give that a try. I can also fall-back to Java 6, as Apple still has packages for Java 6 i386 and x86_64 (both of which I have installed and available). - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJTHijxAAoJEBzwKT+lPKRY4vAQAJXROFkP430767lmFqA1TB8k hQYoFvvj51MUYVt9Xoyv9GW0TYFWcBkVXeGRp5YhDMMr1pgueFaxcXmSEBwccTV3 OvIdqDm+eZFQcFGSm/6kzFMXIwJRcC0tym7PsmvUFYSAUkWGGGDpxpjbU5Yk79ZZ 4KB4c6DcAEUwxcaLi3TTcS6YB1/cZ6VoTy4onjqgMprQ6DhWFieWkfQKIlryamEi APpw407K/qBt79YPoKBrld1Kcbvn3aKDFuJjs4JHMDLtjKRcrWITZXXCStAMe8rk ugIXch0RP25H+XvK3nfmF8kw6MLNNSS3g7rDsYnIPIsQltD0HucL8+c7IoID8842 OuURHAUw1n+Cd6pW3wE+Av9Zivo3iPw72iAI8kZYn/z9T1lbc0M6w4/3e8bKysST /gkExlj+CZ6SPy+qpl47ojX07ZktVosW4zJi7P+KtjxYOzLEnag+0tz0nTeB6kRs jnPNg+cCv+FnWLW43KB3+1QbM8YEaCzhO8DyLYdFi9v+TJ2Hoyp4+wAJjvqLXdm+ OPwlF1UdNiSwENmqgzfMEJ7Fw10fXR8zA3ffXMkvopj5APZe/4UjZRDEEfq8baHe UbBRBtTAft3Za1xOMpuT+RoNzBKVo2YlSCVzlTC2jVlwu9nZAYQLMfTzLKso8zmk tHx/jbDh8g56qXVQClJL =erew -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
