Description Matthias Becker CLA 2020-03-04 03:57:00 EST 
The "Link Handlers" preference page does not show all uri schemes as not registered on macOS Catalina. In addition it takes some time to open the preference page.

The cause seems to be that the output of lsregister did change in macOS catalina.
Comment 1 Matthias Becker CLA 2020-03-04 04:29:08 EST 
lsregister output has changed in various places:

1.) The info block for an application no longer starts with the lines:
BundleClass: kLSBundleClassApplication
Container mount state: mounted
bundle	id:            ####

but with 

bundle id:          Eclipse (0x1238)
class:              kLSBundleClassApplication (0x2)
container:          / (0x4)
mount state:        mounted

2.) path value has changed. It seems that there is now a hex string at the end of the line for path: /Users/myUser/Eclipse.app (0x15b0)

The other parts we use to read the uri scheme information seem to be changed mainly the blocks: 

claim	id:            42056
name:          The adt protocol
rank:          Default
roles:         Viewer  
flags:         url-type  
icon:          
bindings:      adt:

no looks like

claim id:           ABAP Development Tools (0x395c)
localizedNames:     "LSDefaultLocalizedValue" = "ABAP Development Tools"
rank:               Default
bundle:             Eclipse (0x1238)
flags:              url-type (0000000000000040)
roles:              Viewer (0000000000000002)
bindings:           adt:

As far as I see we only evaluate the bindings: line

I this change I simply added an shortened version of my lsregister output.
This can be a good starting point for writing a unit test and fixing this issue.

Let's test this in tomorrow's i-build.
