serverless-java-container

A Java wrapper to run Spring, Spring Boot, Jersey, and other apps inside AWS Lambda.

Runssource: GitHubhomepageJavaApache-2.0commit 75822fea77d6

Java, Apache-2.0 licensed. The project labels itself: api, api gateway, api server, aws, aws lambda, jersey, rest api and serverless.

serverless-java-container runs. An Argusic agent installed it in 5.5 minutes and hit no errors on a clean machine with no GPU, and the whole session was recorded.

All 7 Maven modules build and test successfully under JDK 21 + Maven 3.9.9. The core container library, Jersey adapter, Spring adapter, Spring Boot 4 adapter, and all three archetype generators compile, pass their unit tests, and install cleanly.

What the agent ended up with on a clean machine, in its own words. How this is measured

Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 100 of 100 (the mean of this project's run scores).

What was not measured

The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.

Peak GPU memory
this ran on a CPU machine, so there was no GPU to sample
Behaviour over a long run
each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load

Replay the whole session, every command from a clean machine to this point.

How it was tested

One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.

Strengths and limits

Measured facts, not opinions. How this is written.

What went well

  • Reached a running state on a clean machine, with the session recorded.
  • Installed in 5.5 minutes, faster than the median of the 16 comparable projects Argusic has measured.
  • Nothing broke on the way: zero errors between clone and running.
  • Ran without a GPU, so it does not need one to start.
  • Licensed Apache-2.0, as reported by its host.

What did not, or is not known

  • Measured once so far. A single attempt shows it can run, not that it runs reliably.

Of the 17 api projects Argusic has installed and timed, serverless-java-container was the 9th fastest to reach a running state, and 12 of 17 reached one at all.

What it is a reasonable choice for

  • Trying it on a laptop or a small server: it reached a running state without a GPU.
  • A quick evaluation: it was running 5.5 minutes after the clone.
  • Following its own README: the documented path worked with nothing to fix.

Also tested, in the same area

Every one of these was installed and run by Argusic on a clean machine. Nothing appears here that was not tested.

Questions

Does serverless-java-container run?
Yes. serverless-java-container runs. Argusic installed and launched it on a clean machine in 6 minutes, hitting 0 errors on the way, and recorded the session.
How did Argusic test serverless-java-container?
On a fresh, disposable machine, with every command recorded and the repository pinned at commit 75822fea77d6. One attempt is recorded, and the full method is on the methodology page.
What did it cost to test serverless-java-container?
The run that produced this verdict cost $0.06: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
How long does serverless-java-container take to install?
5.5 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
Does serverless-java-container need a GPU?
Not to start. Argusic reached a running state on a machine with no GPU.
What goes wrong when installing serverless-java-container?
Nothing did, in the recorded run: zero errors between clone and running.
How does serverless-java-container compare with the alternatives?
Of the 17 api projects Argusic has installed and timed, serverless-java-container was the 9th fastest to reach a running state, and 12 of 17 reached one at all.
Where is the evidence for serverless-java-container?
The recorded run is on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
