Fix RAR schema validation for integral numeric schema keywords - #3292
sanjulaonline wants to merge 3 commits into
Conversation
Normalize integer-valued schema keywords before creating the Vert.x JsonObject used for RAR authorization details schema validation. This avoids ClassCastException failures when JSON schema numeric keywords such as minItems, maxItems, minLength, and maxLength are represented as integral Double values. The normalization is recursive, preserves the caller-owned schema map, and only converts non-negative integer-range values for supported schema-size keywords.

The schema normalizer selected values for integer conversion by key name alone. When an authorization detail property was itself named after one of the six supported keywords, its subschema was handed to the numeric converter, returned unchanged and never recursed into. Nested minItems and maxItems values therefore stayed as Double and validation still failed with the ClassCastException reported in wso2/product-is#28292. Gate the keyword conversion on the value actually being a Number so map and collection values continue through the recursive paths. Add regression coverage for keyword named properties, boundary values, keywords nested inside schema lists, caller owned map immutability and unrelated numeric keywords that must never be converted.

Hi @sadilchamishka, could you take a look at this one when you have a moment? This PR has no workflow runs — the only statuses are the CLA check and CodeRabbit, so the build and tests have never actually executed. Could you approve the workflow runs for it? It addresses wso2/product-is#28292 by normalizing the integer-valued JSON Schema keywords ( Happy to make any changes you'd like. |

It seems the list misses minContains and maxContains. A schema using contains with either one may still crash. shall we check that too?

Vert.x 4.5.25 reads both minContains and maxContains through JsonObject#getInteger, and the new regression case reproduced the same Double cannot be cast to Integer failure. I added both keywords to the normalization set and covered successful normalization, caller-map immutability, and maxContains enforcement in eb54bc8. The focused validator suite now passes all 13 tests, and the full RAR suite passes all 45 tests.

@pavinduLakshan The minContains/maxContains review feedback is addressed in eb54bc8, with red-to-green regression coverage and the full RAR suite passing locally. The PR Builder run for the new head is currently awaiting maintainer approval; could you approve it when convenient? |

Thanks for the contribution! Closing this since the issue (wso2/product-is#28292) is being addressed at the framework level in wso2/carbon-identity-framework#8324, which parses authorization details type schemas loaded for RAR validation with integral numbers preserved as integers. That fixes the |
