Description Ori Liel 2017-11-08 07:27:26 UTC
Auto-generated code from 'live-documentation', which validates input, may fail with NPE or IndexOutOfBoundsException when validating collections. 

Pasting comment from JaxrsHelperGenerator.getAttributePath():

TODO: !=null and .isEmpty() checks for collections missing at this point due to complexity in adding them. Only the full check is added, e.g:               


this means the NullPointer or InderOutOfBound exceptions are possible for bad collection input

How Reproducible (always, 100%):

Add disk: POST .../api/disks


This will result in NPE (disk.getLunStorage.getLogicalUnits().getLogicalUnits())

Add disk: POST .../api/disks

This will result in IndexOutOfBoundException

Comment 2 Radim Hrazdil 2017-12-13 16:12:06 UTC
Verified that POST requests in format suggested in the description don't yield NPE or IndexOutOfBoundException, but error message in following format is returned:
    <detail>LogicalUnit  required for add</detail>
    <reason>Incomplete parameters</reason>

Version 4.2.0-0.6

Comment 3 Ori Liel 2017-12-14 06:02:35 UTC
