This is a known bug in the gcj verifier. Eric Blake sent a PR for it
just a few days ago.
The problem is that gcj doesn't correctly notice that an array
implements Cloneable and Serializable. The front end accepts this
code since it has special cases for this.
One workaround for you would be to compile your program from source,
not from .class files.
