Does god resolution of mount points... but...

In doing some testing it was very strange that an entry was omitted.
I am not sure why...

see...

length of esg_dataroot_aa = 15 ? length of esg_dataroot/1 = 14
length of esg_dataroot_aaa = 16 ? length of esg_dataroot/1 = 14
length of esg_dataroot_aaa = 16 ? length of esg_dataroot_aa = 15
length of esg_dataroot_aaaa = 17 ? length of esg_dataroot_aa = 15
length of esg_dataroot_aaaa = 17 ? length of esg_dataroot_aaa = 16
length of esg_dataroot = 12 ? length of esg_dataroot_aa = 15
length of esg_dataroot = 12 ? length of esg_dataroot/1 = 14
length of esg_dataroot/1/2/3 = 18 ? length of esg_dataroot_aa = 15
length of esg_dataroot/1/2/3 = 18 ? length of esg_dataroot_aaa = 16
length of esg_dataroot/1/2/3 = 18 ? length of esg_dataroot_aaaa = 17
length of esg_dataroot/1/2 = 17 ? length of esg_dataroot_aa = 15
length of esg_dataroot/1/2 = 17 ? length of esg_dataroot_aaaa = 17
Adding mountpoint: esg_dataroot/1/2/3 --> /esg/data/one/two/three
Adding mountpoint: esg_dataroot_aaaa --> /esg/data/a/a/a/a
Adding mountpoint: esg_dataroot_aaa --> /esg/data/a/a/a
Adding mountpoint: esg_dataroot_aa --> /esg/data/a/a
Adding mountpoint: esg_dataroot/1 --> /esg/data/one
Adding mountpoint: esg_dataroot --> /esg/data

Resolving /esg_dataroot/1/2/test/foo.nc
Resolved to local path: [/esg/data/one/2/test/foo.nc]

What I entered as the mount map is:
        Map<String,String> m = new java.util.HashMap<String,String>();
        m.put("esg_dataroot/1/2","/esg/data/one/two");
        m.put("esg_dataroot/1/2/3","/esg/data/one/two/three");
        m.put("esg_dataroot","/esg/data");
        m.put("esg_dataroot/1","/esg/data/one");
        m.put("esg_dataroot_aa","/esg/data/a/a");
        m.put("esg_dataroot_aaaa","/esg/data/a/a/a/a");
        m.put("esg_dataroot_aaa","/esg/data/a/a/a");

NOTICE

        m.put("esg_dataroot/1/2","/esg/data/one/two");

is missing from the mount point inventory!
I can reproduce this with other strings! Hmm.....

does "/2" mean something to the comparator?
