--------------------------------------
Resolution: Fixed
> camel-pdf - align Exchange header constant names with Camel naming convention
> -----------------------------------------------------------------------------
>
> Key: CAMEL-23579
> URL: https://issues.apache.org/jira/browse/CAMEL-23579
> Project: Camel
> Issue Type: Improvement
> Components: camel-pdf
> Reporter: Andrea Cosentino
> Assignee: Andrea Cosentino
> Priority: Major
> Fix For: 4.21.0
>
>
> The PDF header constants in
> {{org.apache.camel.component.pdf.PdfHeaderConstants}} use hyphenated string
> values that do not follow the Camel naming convention. Read by
> {{PdfProducer}}:
> * {{DECRYPTION_MATERIAL_HEADER_NAME = "decryption-material"}} - decryption
> password material
> * {{PROTECTION_POLICY_HEADER_NAME = "protection-policy"}} - PDF encryption
> policy
> * {{PDF_DOCUMENT_HEADER_NAME = "pdf-document"}} - PDDocument for append
> * {{FILES_TO_MERGE_HEADER_NAME = "files-to-merge"}} - file list for merge
> Rename to {{CamelPdf<Name>}} ({{CamelPdfDecryptionMaterial}},
> {{CamelPdfProtectionPolicy}}, {{CamelPdfDocument}}, {{CamelPdfFilesToMerge}}).
> h3. Fix shape
> Rename the *string value* of each producer-read header constant to
> {{Camel<Component><Name>}}; keep the Java field name unchanged so routes that
> reference the constants symbolically continue to compile and run. Update
> tests that use the literal string values; regenerate component catalog JSON
> and docs; add an upgrade-guide entry in {{camel-4x-upgrade-guide-4_21.adoc}}
> (and matching 4_18 / 4_14 for backports where the component existed in those
> branches).
> h3. References
> * Tracker: CAMEL-23577
