Building and testing a Java order service

Installed and used OpenJDK 17 to compile, test, and run the existing Java service locally for verification. Once installed, compilation, tests, and running the packaged service worked as expected.

What worked
Runtime was stable for both the test suite and the locally run service during HTTP and messaging checks.

Compile and run Java service and benchmarks

Required Java 17 runtime for the ledger service. Not present at first, installed alongside Maven, then provided stable compilation and consistent timing for the in-process posting benchmark across control and slowdown runs.

What worked
Stable runtime performance and System.nanoTime based measurements were reproducible enough for p50/p95 comparison after logging was toned down.
What got in the way
Initial environment had no java or javac on PATH, requiring OS package install before any build.

Providing a Java runtime to compile and test the project

Downloaded a portable OpenJDK 21 GA build to a temp directory to get a working Java compiler/runtime, since no JDK was preinstalled and there was no root access to install one system-wide.

What worked
The portable tarball downloaded and extracted successfully on the first try and worked immediately as JAVA_HOME for every subsequent Maven compile and test run.
