      A DESCRIPTION OF THE PROBLEM :
      The following chain returns a ValidatorException with the message "Violated path length constraints" in 1.6.0_18.

      2010-01-29 13:49:20,219 INFO [http-127.0.0.1-8080-1] STDOUT:152 chain [0] = [
      ...
      [8]: ObjectId: 2.5.29.19 Criticality=false
      BasicConstraints:[
        CA:false
        PathLen: undefined
      ]


      2010-01-29 13:49:20,266 INFO [http-127.0.0.1-8080-1] STDOUT:152 chain [1] = [

      ]


      2010-01-29 13:49:20,329 INFO [http-127.0.0.1-8080-1] STDOUT:152 chain [2] = [

      [8]: ObjectId: 2.5.29.19 Criticality=true
      BasicConstraints:[
        CA:true
        PathLen:1
      ]


      2010-01-29 13:49:20,360 INFO [http-127.0.0.1-8080-1] STDOUT:152 chain [3] = [
      ...
      [8]: ObjectId: 2.5.29.19 Criticality=false
      BasicConstraints:[
        CA:true
        PathLen:2147483647
      ]

      The problem occurs because the PathLen constraint in chain[2] has the value 1 and there is a CA certificate (chain[1]) that follows this certificate in the chain.

      The specification says the following about the PathLen constraint: "it gives the maximum number of CA certificates that may follow this certificate in a certification path", so the chain should be accepted.

      The problem only occurs in update 18.
