feat(dotAI): upgrade LangChain4j to 1.15.1 and enable Azure gpt-image-1 support

[ihoffmann-dot]

Summary

• Bump langchain4j.version from 1.0.0 to 1.15.1 in bom/application/pom.xml
• Add langchain4j-open-ai-official dependency to dotCMS/pom.xml
• Replace deprecated AzureOpenAiImageModel with OpenAiOfficialImageModel (Microsoft Foundry) in AzureOpenAiModelProviderStrategy — enables gpt-image-1 on Azure
• Fix VertexAiModelProviderStrategy imports: Gemini classes moved to dev.langchain4j.model.vertexai.gemini in 1.15.1

Notes

• AzureOpenAiImageModel only supported dall-e-3, which Azure deprecated in June 2025. OpenAiOfficialImageModel with isMicrosoftFoundry(true) is the correct replacement for Azure image generation going forward.
• gpt-image-1 supports sizes 1024x1024, 1024x1536, 1536x1024 on Azure.
• The apiVersion field in providerConfig.image should be 2025-04-01-preview or newer for gpt-image-1 support.
• All other providers (OpenAI, Vertex AI) are unaffected by this change.

• Read rollback-unsafe categories reference
• Analyze diff against unsafe categories
• Apply label

Result: ✅ Safe To Rollback

The label AI: Safe To Rollback has been applied.

All 4 changed files are pure dependency version bumps and internal AI model provider code changes. A full scan against every rollback-unsafe category found no matches:

Category	Check	Result
C-1 Structural Data Model	No runonce tasks, no schema migration	✅
C-2 Elasticsearch Mapping	No ES mapping code changes	✅
C-3 Content JSON Model Version	No CURRENT_MODEL_VERSION bump	✅
C-4 DROP TABLE / DROP COLUMN	No DDL drop statements	✅
H-1 One-Way Data Migration	No data transformation	✅
H-2 RENAME TABLE / COLUMN	No renames	✅
H-3 PK Restructuring	No PK changes	✅
H-4 New Content Type Field	No FieldTypeAPI registrations	✅
H-5 Storage Provider Change	No StoragePersistenceProvider changes	✅
H-6 DROP PROCEDURE / FUNCTION	No stored procedure drops	✅
H-7 NOT NULL without default	No schema changes at all	✅
M-1 Column Type Change	No DDL changes	✅
M-2 Push Bundle Format	No *Bundler.java changes	✅
M-3 REST / GraphQL API Contract	No endpoint or response shape changes	✅
M-4 OSGi Public Interface	No exported interface changes	✅

The changes are limited to:

• bom/application/pom.xml: LangChain4j version bump 1.0.0 → 1.15.1
• dotCMS/pom.xml: New langchain4j-open-ai-official dependency (additive only)
• AzureOpenAiModelProviderStrategy.java: Internal model provider swap (AzureOpenAiImageModel → OpenAiOfficialImageModel) — no DB, ES, or API contract impact
• VertexAiModelProviderStrategy.java: Import package path fix — no behavioral change

Rolling back to the previous release requires no database interaction, no Elasticsearch reindexing, and no client-side changes.
