Context and other notes
- Warning observed: Dockerfile: FromAsCasing: 'as' and 'FROM' keywords' casing do not match (line 2)
- Version-related info: npm notice New patch version of npm available! 11.11.0 -> 11.11.1
- The log also shows the broader apt-get install step completing, but no missing packages/files are reported; the failure is due to the pre-existing yarn binary during global install.

  - Process spawn error. Is java in the path?
  - spawn java ENOENT
  - Command failed with exit code: 1

- Missing packages or files mentioned
  - Java runtime not found in PATH (ENOENT for java). The error asks if java is in the path, indicating the Java executable is missing.

- Version mismatch information
  - Warning: Resolution field "jsdom@22.1.0" is incompatible with requested version "jsdom@^20.0.0"

- Summary of impact
  - The build fails at the last stage (builder 9/9) due to missing Java, causing yarn build to exit with code 1.

- Missing packages or files mentioned:
  Missing file: /workspace/scripts/flow/createFlowConfigs.js

- Version mismatch / warnings observed:
  - warning Resolution field "jsdom@22.1.0" is incompatible with requested version "jsdom@^20.0.0"
  - warning "eslint-plugin-ft-flow@2.0.3" has unmet peer dependency "@babel/eslint-parser@^7.12.0"
  - warning "eslint-plugin-ft-flow@2.0.3" has incorrect peer dependency "eslint@^8.1.0"
  - warning "eslint-plugin-react@6.10.3" has incorrect peer dependency "eslint@^2.0.0 || ^3.0.0"

- Context note:
  The build fails during the Yarn install step due to the missing createFlowConfigs.js script, not due to network or dependency fetch issues. Node.js version in the image is 25.x (v25.8.1).
