Bug? nextobject hangs

[dcoun]

Hi

s=$" { "test":{ "as":"1"  } }"$
                Try
                Dim jj As JSONParser
                Log(s) : jj.Initialize(s) 
                Log(jj)
                Log(jj.IsInitialized)
                dim a as map
                a=jj.nextobject
                Catch : Log(LastException) : End Try

code hangs as jj.nextobject. If I stop debugger I get the red errors following:

*** Service (starter) Create ***
** Service (starter) Start **
0
{ "test":{ "as":"1" } }
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
(JSONTokener) at character 0 of { "test":{ "as":"1" } }
true

See this tool for help parsing a jjon
http://basic4ppc.com:51042/json/index.html

Dim parser As JSONParser
parser.Initialize($" { "test":{ "as":"1"  } }"$)
Dim root As Map = parser.NextObject
Dim test As Map = root.Get("test")
Dim as As String = test.Get("as")

Works fine here. Tested with this code:

Sub Service_Create
   Dim s As String=$" { "test":{ "as":"1"  } }"$
   Try
       Dim jj As JSONParser
       Log(s) : jj.Initialize(s)
       Log(jj)
       Log(jj.IsInitialized)
       Dim a As Map
       a=jj.nextobject
   Catch : Log(LastException) : End Try
End Sub

To my B4A 8.3 it hangs with 2 different devices
In emulators I get
adb: failed to install myprogram_RAPID_DEBUG.apk: Failure [INSTALL_FAILED_NO_MATCHING_ABIS: Failed to extract native libraries

It was a case in a select inside a for/next loop.
I put the above code outside
it still hangs and when I Stop the debuging I am getting:

it works now, but I changed nothing and I do not why it works now

My bet is, when you stop the debugger and then restart the compilation, the IDE makes a "clean-up" of the cached "start-pause-resume" action and cleans up any "trash" info left behind...

To be honest, I restarted many times the B4A IDE. I did not restart the b4A bridge. But it was fixed, after taking a walk
