A UNO sequence type with a given component type is mapped to the Java array type with corresponding component type.

• UNO sequence<long> is mapped to Java int[].
• UNO sequence< sequence<long> > is mapped to Java int[][].

Only non-null references to those Java array types are valid. As usual, non-null references to other Java array types that are assignment compatible to a given array type can also be used, but doing so can cause java.lang.ArrayStoreExceptions. In Java, the maximal length of an array is limited; therefore, it is an error if a UNO sequence that is too long is used in the context of the Java language binding.
