spring boot embedded tomcat doesn't start with jcifs smb library - spring-boot

Question

I have a standalone java application which uses jcifs library for doing SMB operations. The standalone application uses spring boot. This application works fine and is able to meet the requirements.
I have to convert this standalone application to a restful service. I thus used spring boot starter with embedded tomcat. The converted application compiles fine but when I start the application, the embedded tomcat doesn't start and gives below error.
I have narrowed the problem to inclusion of jcifs library. when I remove it the embedded tomcat starts fine and when I include it then get the below error.
The jcifs dependency is as follows:
compile group: 'jcifs', name: 'jcifs', version: '1.3.17'
Please let me know what could be the problem or any any pointers. I am running against a very tight timeline and thus any help/pointers will be very much appreciated.
The error is:

You just have do exclude the "servlet-api" dependency from jcifs library, it is conflicting with tomcat default servlet api.
In maven it would be something like:
<dependency>
<groupId>org.codelibs</groupId>
<artifactId>jcifs</artifactId>
<version>1.3.18.2</version>
<exclusions>
<exclusion>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
</exclusion>
</exclusions>
</dependency>
The exclusion serves well also when using spring-integration-smb library.
