…le initialized to DECRYPT_MODE The DECRYPT_MODE suppression in SecureInitializationFinder relied on asConstant() to resolve the operation mode, which only works for compile-time constants. A non-final variable initialized to Cipher.DECRYPT_MODE was not resolved, causing the suppression to silently fail and a FP to be raised. Added resolveIntConstant() which falls back to inspecting the variable's declaration initializer when asConstant() returns empty. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
