Java related error encountered while running gatk PathSeqPipelineSpark

Hi,

I am trying to test the pathseq tutorial following the tutorial on this link

I ran the following commands

bioinfo@bioinfo$ conda activate gatk
(gatk) bioinfo@bioinfo$ gatk PathSeqPipelineSpark \
>     --input test_sample.bam \
>     --filter-bwa-image hg19mini.fasta.img \
>     --kmer-file hg19mini.hss \
>     --min-clipped-read-length 70 \
>     --microbe-fasta e_coli_k12.fasta \
>     --microbe-bwa-image e_coli_k12.fasta.img \
>     --taxonomy-file e_coli_k12.db \
>     --output output.pathseq.bam \
>     --scores-output output.pathseq.txt

And encountered below error:
