Parsing multidimensional array

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create multidimensional array (Double[][][] weight)
2. Dump it. My dump looks like:

!!jailibrary.BasicStructure
function: !!jailibrary.SigmoidalFunction {}
hiddenLayersCount: 1
hiddenNeuronsSizes: [2]
inputLayerSize: 4
outputLayerSize: 4
weights:
- - [-5.7855340159344975, 6.391058034908343, -4.898270739235223, 
3.80241100406204, -0.4181628620974109]
  - [-4.780729632685992, 5.185100785736257, 5.460538218689736, -6.127283837890756, -0.04953490116064775]
- - [-15.297894284897312, -14.678007960620098, 6.873882038095056]
  - [13.37170571894871, 12.882660101636331, -19.820490340355864]
  - [-14.804057108901775, 14.621970628181957, -7.5768397188668395]
  - [14.715839948961465, -15.47193956749274, -7.262953745888246]

3. Try to parse it. 

What is the expected output? What do you see instead?
Expected: created Object.
Instead:

Exception in thread "main" Can't construct a java object for 
tag:yaml.org,2002:jailibrary.BasicStructure; exception=Cannot create 
property=weights for JavaBean=jailibrary.BasicStructure@15ad1da; array element 
type mismatch
 in 'string', line 1, column 1:
    !!jailibrary.BasicStructure
    ^
What version of SnakeYAML are you using? On what Java version?
SnakeYAML: 1.11, Java: SE 1.7

Arrays of primitives are not supported. It is connected to issue 
http://code.google.com/p/snakeyaml/issues/detail?id=135

There is no planning to support it in the nearest future. This is due to no 
support for arrays in the Java Introspection API.

It was not array of primitives. I was array of Double's, not double's: 
Double[][][] weights.

It is the same problem. Java Introspection API does not provide the type of the 
elements of arrays at runtime.
To make it more clear: Java does not have multidimensional arrays. What you 
provide is an array where the values are primitives (arrays).

You can create the array as list of lists and then assign it to your business 
object. But it requires to code your own way to create an instance.

Since there is no clarification form the reporter the issue is closed
