Ok. I'm just trying to figure out how to test the compilation timeout
without having a 5-second script. I would like to set the timeout to 1ms.
Even using the deprecated config doesn't seem to work for me.
```
compilerCustomizerProviders: {
"org.apache.tinkerpop.gremlin.groovy.jsr223.customizer.CompilationOptionsCustomizerProvider":
[1]}
```
Error:
```
[WARN] ScriptEngines - Could not instantiate CompilerCustomizerProvider
implementation
[org.apache.tinkerpop.gremlin.groovy.jsr223.customizer.CompilationOptionsCustomizerProvider].
It will not be applied.
java.lang.IllegalStateException: Could not configure
org.apache.tinkerpop.gremlin.groovy.jsr223.customizer.ConfigurationCustomizerProvider
with the supplied options [1]

> Improve script compilation process and include metrics

> Key: TINKERPOP-1644
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1644
> Project: TinkerPop
> Issue Type: Improvement
> Components: groovy
> Affects Versions: 3.2.4
> Reporter: Bryn Cooke
> Assignee: stephen mallette
>
> Currently there is no synchronisation around script compilation. This means
> that if a particularly heavy script is in use, many threads may end up
> compiling the same script.
> It would seem like a good idea to have some some sort of synchronisation to
> prevent ever getting to this stage.
> In addition, there will be cases where users will repeatedly submit broken
> scripts to the server. In this case it is useful to log the error the first
> time the script compilation is attempted and then cache the error for
> subsequent runs.
> Finally I have found some scripts take in excess of 30 seconds to compile. To
> aid performance debugging the script compilation times should be included in
> the logs.
