java.lang.ClassFormatError: LineNumberPreservingDOMParser

[gandra404]

Hi!

I have a problem with SpringSource Tool Suite, Version: 2.9.2.RELEASE, Build Id: 201205071000
When I create new mvc template project immediately after creation the project has errors:

java.lang.ClassFormatError: org/springframework/ide/eclipse/core/io/xml/LineNumberPreservingDOMParser

This problem occures in 2 files:

• root-context.xml
• servlet-context.xml

Any idea how to solve this error?

Hey!

This error looks a bit dangerous to me. If it doesn't go away when you do a clean build the project "Project -> Clean", then I would re-install STS. The error looks like the class file of an STS plugin got corrupted.

HTH,
