> A FrameBlock reset, e.g., on feeding the same reuse frame block multiple times into slice
with different data sizes, currently does not work properly, leading to an ArrayIndexOutOfBoundsException
on the actual data copy if the target is larger than then previously allocated block.
> {code}
> java.lang.ArrayIndexOutOfBoundsException
>         at java.lang.System.arraycopy(Native Method)
>         at org.apache.sysml.runtime.matrix.data.FrameBlock$StringArray.set(FrameBlock.java:1280)
>         at org.apache.sysml.runtime.matrix.data.FrameBlock.sliceOperations(FrameBlock.java:884)
> {code}
