I hereby nominate Christian Hagedorn (chagedorn) to JDK Reviewer.

Christian is a member of the HotSpot Compiler Team at Oracle and contributed 47 changes to the JDK
project [1]. At least 35 changes are significant and affect complex code in the JIT compilers.

Christian has worked on both C1 and C2, acquiring expert knowledge in key areas (for example, loop
unswitching and superword optimizations). He investigated and fixed several highly complex and
long-standing issues in the code base and improved maintainability and debugability of the JITs. All
the while, Christian is constantly updating and extending the sparse documentation, making life
easier for other engineers.

Votes are due by 09:00 UTC, July 17th, 2020.

Only current JDK Reviewers [2] are eligible to vote on this nomination. Votes must be cast in the
open by replying to this mailing list.

For Lazy Consensus voting instructions, see [3].
