I'm trying to run Tomcat 9 (have v8 running fine) but it doesn't start due to a missing class that I can't locate anywhere or in any lib. I have Tomcat 9 installed out of the box and it doesn't run even from the command like with a "catalina run". Upon Tomcat startup I am getting the following No Class Found error. Any help would be appreciated. java.lang.NoClassDefFoundError: org/apache/tomcat/util/file/ConfigurationSource at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Unknown Source) at java.lang.Class.getConstructor0(Unknown Source) at java.lang.Class.getConstructor(Unknown Source) at org.apache.catalina.startup.Bootstrap.init(Bootstrap.java:264) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:461) Caused by: java.lang.ClassNotFoundException: org.apache.tomcat.util.file.ConfigurationSource at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 6 more

Looks like I might have had a bad download from a Tomcat mirror. I downloaded version 9.0.14 from the tomcat archive and it words fine now.

CPU at 100% most of the time.
Hi guys, Lately I have been having a problem with my PC. On several occasions my PC has slowed right down and virtually ground to a halt. When I've checked it with Task Manager, it shows that the processor is running at 100%, and that there are over 40 processes running at once. This can happen...
