 Using EVM Tool in execution-specification-tests
 -----------------------------------------------
 
-To use EVM Tool in Execution Spec tests it is recommended that you use
-the GraalVM build, as the framework incurs significant startup penalties
-for each invocation when run via the Java runtime.

+First you need a Java 21+ JDK installed, if not already installed.
 
 It is recommended you install [SDKMAN](https://sdkman.io/install) to
-manage the graalVM install, homebrew has issues with native attributes
-and code signing.
+manage the jvm install.
 
 ```zsh
-sdk install java 22.3.r17-grl 
-sdk use java 22.3.r17-grl
+sdk install java 21.0.3-tem 
+sdk use java 21.0.3-tem
 ```
 
-You can also manually install GraalVM from
-the [GraalVM website](https://www.graalvm.org/downloads)..
-
-Once GraalVM is installed you use the `nativeCompile` target.
+Once a JVM is installed you use the gradle target:
 
 ```zsh
-./gradlew nativeCompile 
+./gradlew installDist -x test
 ```
 
 The resulting binary
-is `./ethereum/evmtool/build/native/nativeCompile/evmtool`
+is `build/install/besu/bin/evmtool`
 
 If the testing repository and besu are installed in the same parent
 directory, the command to run the execution tests is
 
 ```zsh
-fill -v tests --evm-bin ../besu/ethereum/evmtool/build/install/evmtool/bin/evm 
+fill -v tests --evm-bin ../besu/build/install/besu/bin/evmtool 
 ```
 
 Assuming homebrew and SDKMan are both installed, the complete script is
 
 ```zsh
-sdk install java 22.3.r17-grl 
-sdk use java 22.3.r17-grl
+sdk install java 21.0.3-tem 
+sdk use java 21.0.3-tem
 git clone https://github.com/hyperledger/besu
 cd besu
-./gradlew nativeCompile
+./gradlew installDist -x test
 cd ..
 
 brew install ethereum solidity
+solc-select install latest
+solc-select use latest
 git clone https://github.com/ethereum/execution-spec-tests
 cd execution-spec-tests
 python3 -m venv ./venv/
 source ./venv/bin/activate

+pip install -e .\[docs,lint,test\]
 
-fill -v tests --evm-bin ../besu/ethereum/evmtool/build/install/evmtool/bin/evm
+fill -v tests --evm-bin ../besu/build/install/besu/bin/evmtool
 ```
 
-If you don't want to use the GraalVM tool the binary that is compatible
-is generated by the `ethereum:evmtool:installdist` target and is located
-at `./ethereum/evmtool/build/install/evmtool/bin/evm`
-
-Why not GraalVM for everything?
--------------------------------
-
-Using GraalVM in execution-spec-tests results in over 20x performance
-increase in execution. It will be faster to build GraalVM from scratch
-and run the execution-spec-tests than to run just the Java version.
-
-It is demonstrably faster to run the Java version for a node.
-All the test execution gains are the result of reduced startup
-penalties. Larger benchmarks will show that performance intensive EVM
-code will be slower in GraalVM than the Java version due to the adaptive
-compiler.
-
-For contracts that execute 30 million gas in small operations it is
-often faster to run the Java EVMTool than the GraalVM EVMTool, including
-startup penalty. The execution tests focus on smaller VM tests that
-demonstrate specification conformance.
-
-We would also need to reconsider some library choices. GraalVM does not
-work with Log4J, and we would have to ban that library across Besu and
-all dependents. Libraries such as Netty also have some problematic entry
-points that interact poorly with how SLF4J needs to initialize.
