Automated review summary:

No blocking issues found. I reviewed the single changed FE test file and the surrounding CreateResourceCommand / CreateResourceInfo.validate() path. The patch is limited to JMockit fixture setup for Env and SystemInfoService in CreateResourceCommandTest, and I did not find a session/config leak, mock-scope issue, optimizer/rewrite impact, or duplicate concern from existing review context.

Critical checkpoints:

• Required AGENTS.md files: none were listed for this PR.
• Existing inline review context: no existing inline comments or replies were present.
• User focus: no additional user-provided review focus.
• Whitespace/style: git diff --check HEAD -- fe/fe-core/src/test/java/org/apache/doris/nereids/trees/plans/commands/CreateResourceCommandTest.java passed.
• Runtime validation: targeted FE test execution could not be completed in this runner because generated-source failed before tests with missing thirdparty/installed/bin/protoc; a separate Maven attempt timed out during dependency resolution before compilation/test execution.

Subagent conclusions:

• optimizer-rewrite: no candidates; convergence round 1 returned NO_NEW_VALUABLE_FINDINGS.
• tests-session-config: no candidates; convergence round 1 returned NO_NEW_VALUABLE_FINDINGS.
• Final inline comment set: empty, so this is a summary-only review.
