OS: Windows 10
Java Version: 1.8.0_121-b13
Server Version: Apache Tomcat/8.0.32
I'm very new at Sakai and I've been trying to use it as a part of a homework. At first, I've tried to install it from source. Unfortunately, it failed to build at samigo-services every time. So, I've decided to install its binary by this guide: https://confluence.sakaiproject.org/pages/viewpage.action?pageId=106792016
Java, Tomcat and Sakai-bin's installations were successful. But as I started the server by startup.bat, I've started to get all these exceptions since it has started extracting *.war files from sakai-bin. Tomcat server runs fine in the end, but these deployed webapps fail to start.
Excerpt from catalina.log:

I'm mostly clueless about these logs but, I'm suspecting that these logs indicate why these deployed webapps simply don't start.
How can I fix these errors and make these webapps start successfully?
Thanks.
These look like the errors discussed recently on the sakai-dev thread here. The solution was
For Sakai 11.3 you should use tomcat 8.0.32, for Sakai 11.4 you can use tomcat 8.0.43. Very little testing is done on Windows and if all else fails installing Tomcat and Sakai in a Linux Virtualbox should eliminate most possible problems.
