How to deal with Findbugs error "Classfile header isn't 0xCAFEBABE in"

findbugs

(Stas Roshkolts) #1

Hello,
After upgrade Sonarqube server to version 6.7.4 and its compatible Findbugs plugin v.3.7 we get next error during the Sonar check:
Caused by: edu.umd.cs.findbugs.classfile.InvalidClassFileFormatException: Classfile header isn’t 0xCAFEBABE in ClassName.class

How can we get rid of this error?
