Hi All:
I reported several months ago, but the error does not disappear (and I cannot find my old posting).
So, here details again:

This page: https://coderanch.com/forums

Gives me stack trace (see attached screenshot) after a delay

No stack trace on other pages.

It's does not annoy me too much, I am fine with that, but thought you might be interested.

Maybe it relates somehow to settings in my profile or cookies, if nobody else does not see it.

[EDIT] Found, this was original note: https://coderanch.com/t/707357/stack-trace-web-browser
Feel free to delete this thread as duplicate, or move the message to that thread...

No books exist for this exam,
as far as I understand test creators mostly used Java EE tutorial and specifications (JSRs).

You are not allowed any document/book/specification during exam.

Only blank plastic board and marker, which you return when you're done.

I'm going to take the same exam later this month.
Witch book do you recommend? is the course provided by oracle worth it?


Check the free study notes for 1Z0-817, the link in my signature.

1Z0-815 exam has a new topic about Modules: Understanding Modules

You can check my free study guide for 1Z0-817 which also covers this objective: http://java.boot.by/ocpjd11-upgrade-guide/

[UPD] You will find in my guide detailed description of this 1Z0-815 topic too: Use local variable type inference

Congratulation Chelios !

You must be the first here who taken 1Z0-817 :-)
Congratuations, Dmitry !

Great score !

LOL, I also thought there was no OCA 6, but in fact it was:

Oracle Certified Associate, Java SE 5/SE 6 1Z0-850 Java SE 5 and 6, Certified Associate

(discontinued a year ago, btw)
Hi Scott !
I wonder what sort of questions were about Modules topic.
Are they only technical ones, with code snippets?
Because there is one objective "Describe the Modular JDK" - seems it's more theoretical.
check which user runs WAS process in OS
run "crontab -l" as that user
inspect if WAS stopped by cron
