Error in VCF test files

[markwoon]

Several failed/ conformance fixtures under test/vcf/{4.1,4.2,4.3}/ use
##CauseOfFailure=Non-valid URL for an ##assembly=/##pedigreeDB= value whose only
distinguishing feature is a numeric-looking hostname (8080): ftp://8080:8080/not-valid/host/to/file.fastq

That string is syntactically valid per RFC 3986 (a reg-name may be all-digits) and passes all URL validators I tried (python, java, online validators).

Are these tests supposed to fail because the URL is syntactically invalid, or that it doesn't actually point to anything? I'm guessing the former since it says not-valid/host and I don't the parser should be expected to make a network call to test the URL.

Affected fixtures

##assembly=ftp://8080:8080/not-valid/host/to/file.fastq

File	##fileformat=	##CauseOfFailure=
test/vcf/4.1/failed/failed_meta_assembly_001.vcf	VCFv4.1	Non-valid URL
test/vcf/4.2/failed/failed_meta_assembly_001.vcf	VCFv4.3	Meta-data entry is not a key-value pair
test/vcf/4.3/failed/failed_meta_assembly_001.vcf	VCFv4.3	Meta-data entry is not a key-value pair

Note: test/vcf/4.2/failed/failed_meta_assembly_001.vcf lives under the 4.2/ directory but internally declares VCFv4.3.

##pedigreeDB=ftp://8080:8080/not-valid/host/to/pedigreeDB

File	##fileformat=	##CauseOfFailure=
test/vcf/4.1/failed/failed_meta_pedigreedb_002.vcf	VCFv4.1	Non-valid URL
test/vcf/4.2/failed/failed_meta_pedigreedb_002.vcf	VCFv4.2	Non-valid URL
test/vcf/4.3/failed/failed_meta_pedigreedb_002.vcf	VCFv4.3	Non-valid URL
