Undeclared/uncaught exception in Fasta Parser

If you feed the fasta parser (code from cookbook) with an empty file, you get a
java.lang.ArrayIndexOutOfBoundsException: 0
        at org.biojava3.core.sequence.io.GenericFastaHeaderParser.parseHeader(GenericFastaHeaderParser.java:111)
        at org.biojava3.core.sequence.io.GenericFastaHeaderParser.parseHeader(GenericFastaHeaderParser.java:60)
        at org.biojava3.core.sequence.io.FastaReader.process(FastaReader.java:136)


Code:

FileInputStream inStream = new FileInputStream(inputFileName);
       FastaReader<DNASequence, NucleotideCompound> fastaReader =
               new FastaReader<DNASequence, NucleotideCompound>(
               inStream,
               new GenericFastaHeaderParser<DNASequence, NucleotideCompound>(),
               new DNASequenceCreator(DNACompoundSet.getDNACompoundSet()));
       LinkedHashMap<String, DNASequence> originalSeqs =
fastaReader.process(); //boom!

I believe this exception should either be caught and converted to an
IOException or declared.

ps: I also ran into an OutOfMemoryError, I tried MSA with approx.
1000+ sequences :D even though I gave java 4000M - are there any
metrics I can use before starting the MSA to determine If it can work?
