*Code snippet of where* {*}ArrayIndexOutOfBoundsException occurs{*}{*}:{*}
{code:java}
int idx = 0;

for (int i = 0; i < erasedDataIndexes.length; i++) {
  toEraseChunks[idx ++] = dataChunks[erasedDataIndexes[i]];
  dataChunks[erasedDataIndexes[i]] = null;
}

for (int i = 0; i < erasedParityIndexes.length; i++) {
  toEraseChunks[idx ++] = parityChunks[erasedParityIndexes[i]];
  parityChunks[erasedParityIndexes[i]] = null;
}{code}
 

*Solution:-*

We propose to add a check to prevent the java.lang.ArrayIndexOutOfBoundsException.

We also propose fixing the exception type from IllegalArgumentException to HadoopIllegalArgumentException in _DecodingState_ class as done in several places around that code.

> The code throws an unhandled ArrayIndexOutOfBoundsException in the method _backupAndEraseChunks_ of _TestCoderBase_ class when it tries to access the out of bound indexes in _dataChunks_ and _parityChunks_ array.
