Embedded Tomcat fails to start due to UnrecoverableKeyException

My embedded tomcat server fails to start due to some problem related to the keystore.
I've found lots of posts related to this issue in stackoverflow and similar platforms. Most of the suggested solutions imply key and keystore password mismatch. That's not the case. The passwords are the same.
My server is built on base of jhipster and it starts successfully with another keystore issued for our organisation.
spring boot version: 1.3.3.RELEASE
spring batch version: 2.2.0.RELEASE
spring beans version: 4.2.5.RELEASE
tomcat embed version: 8.0.32
jre version: 1.8.0_171-b11
I've built a simple project based on embedded tomcat, that contains nothing but a single rest controller. This simple server starts successfully with the
same keystore that causes my server to fail.
The stacktrace is very similar to most posts related to the keystore issue:

I am not able to understand why it is not able to find the class although, I have it in my maven dependencies
spring-boot-autoconfigure-1.2.3.RELEASE.jar
Any help would be highly appreciated.

You seem to have included incorrect jar. Use spring-boot-autoconfigure-1.2.3.RELEASE.jar instead of spring-boot-autoconfigure-1.2.3.RELEASE-sources.jar
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-autoconfigure</artifactId>

It's a 404 error but I don't know why because I included all the tile libraries. Specifically, I am using struts2-core-2.1.6.jar and tiles-core-2.0.6.jar, build path is included and tiles listener is configured
<listener>
<listener-class>org.apache.struts2.tiles.StrutsTilesListener</listener-class>
</listener>
More details: I am using struts-2.3.16.1 library and included
tiles-api-2.1.2.jar
tiles-compat-3.0.1.jar
tiles-core-2.0.6.jar
tiles-jsp-2.1.2.jar
tiles-servlet-3.0.1.jar
commons-beanutils-1.8.0.jar

It doesn't deploy. I already checked the classpath, Spring and Log4j XML files and all looks good, and I'm running out of ideas about what else to look for.
Any ideas? Any comments will be appreciated :)

Case closed!
Turns out, another spring application was not deploying correctly, which, I think, caused static logs for bean factories to mess up other deployments due the static nature of log references.
Hope this helps anybody else. Weird log messages didn't help. Thanks guys for your comments.

Upgrading to Struts 2.3.15 - Convention Plugin cause crash on startup

I'm in the process of upgrading my Struts2 installation to 2.3.15. After adding the struts2-convention-plugin-2.3.15.jar my web-app fails to start. The relevant part of the exception listing is;
Caused by: Attribute "order" must be declared for element type "struts". - jar:file:/H:/apache-tomcat-7.0.20/wtpwebapps/FaultmateGenesis-Server/WEB-INF/lib/struts2-convention-plugin-2.3.15.jar!/struts-plugin.xml:29:20

Anyone got any idea what's going on?

The full trace is;

You should use the correct doctype in the struts.xml
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
