NoClassDefFoundError every second restart of Tomcat

Question

Currently we are facing a strange issue. We have a big application which is deployed as ROOT.war in the webapp directory (no other applications). Tomcat (8.0.32) unpacks the war while starting. It starts as a Windows service.

When we stop the service and start it again then the NoClassDefFoundError occurs (one of our own classes, every time the same). After a new stop/start it does work. Stop/Start -> Doesn't work. Stop/Start -> Does work and so on...

We develop on Eclipse and we don't face this issue during development.

I don't have a clue how to fix this. I tried the reloadable=false on the context and tried autoDeploy=false unpackWars = true on the Host.

We are using Spring/Hibernate.

    Message: Can't instantiate page using constructor 'public my.package.MyPage(org.apache.wicket.request.mapper.parameter.PageParameters)' and argument 'p=[MyOtherPage], userName=[abc1]'. An exception has been thrown during construction!

Note: I renamed our company packages...

On line 114 of MyPage we are creating a new panel of type MyPanel.

Answer 1

Had the exact same issue, we had a static final String in our custom class

private static String USERNAME = SecurityContextHolder.getContext().getAuthentication().getName();

Removing the final fixed it.

Answer 2

maybe you can try put spring-security-core-3.1.0.RELEASE.jar to the tomcat's lib dir

Answer 3

Problem was a static { .. } block in my MyPanel.java Nothing strange happened there but it was causing this issue. Thanks for helping!
