Reading tabix from ftp

[dariober]

It appears tabix files from ftp cannot be read. For example, read a vcf file from 1000genomes:

import htsjdk.samtools.seekablestream.SeekableStream;
import htsjdk.samtools.seekablestream.SeekableStreamFactory;
import htsjdk.tribble.readers.TabixReader;

String ftp= "ftp://ftp.1000genomes.ebi.ac.uk/vol1/ftp/phase1/analysis_results/input_call_sets/ALL.wex.union_illumina_wcmc_bcm_bc_bi.20110521.snps.exome.sites.vcf.gz";

// Here it hangs:
TabixReader tabix= new TabixReader(ftp);

// In particular, this seems to hang:
SeekableStream stream= SeekableStreamFactory
    .getInstance()
    .getBufferedStream(SeekableStreamFactory.getInstance()
    .getStreamFor(ftp));

Would be good to post on biostars/htsjdk list
