Public bug reported:
$ jardiff -f old/usr/share/java/tomcat10-embed-core-10.1.16.jar -t

java.lang.UnsupportedOperationException: NestHost requires ASM7

Just for demonstration the same jar has been used:
http://launchpadlibrarian.net/700742608/libtomcat10-embed-
java_10.1.16-1_all.deb.
Tested on source pkg: noble 0.2-5.1
Bumping version of libasm-java maybe required.
But, the source code is still using ASM5:
jardiff-0.2/src/java/org/osjava/jardiff/ClassInfoVisitor.java:
super(Opcodes.ASM5);
```
public ClassInfoVisitor() {
super(Opcodes.ASM5);
}
```
So, to support latest versions of java, ASM version needs to bumped to
use ASM7 or above (Java 11 support would be nice)
