> 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)
