[Alexander Farber]

Hello,

after upgrading from Jetty version 9.4.6.v20170531 to 9.4.8.v20171121 I
unfortunately see the following errors when starting it on CentOS Linux 7
by the command

/usr/bin/java -Djdbc.drivers=org.postgresql.Driver -jar
/usr/share/java/jetty-distribution-9.4.8.v20171121/start.jar
jetty.home=/usr/share/java/jetty-distribution-9.4.8.v20171121

Is it a known issue in Jetty 9.4.8.v20171121 or have I done something wrong
when compiling my WAR file with the pom.xml file:

Nevermind, sorry -

I have fixed my problem by adding the following to WAR pom.xml:

<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>

As described in the
https://www.eclipse.org/jetty/documentation/9.4.x/maven-and-jetty.html

After that the WEB-INF/lib/javax.servlet-api-3.1.0.jar has disappeared from
my WAR file contents

Regards
Alex
