Concrete ScriptExecutor for Kotlin scripts. Compiles and evaluates Kotlin source using the kotlin.script.experimental API. Handles fat JAR classpath resolution via JarExtractor, variable binding via KotlinScriptContext, and script execution with 300-second timeout and proper error diagnostics.

Architecture

Compilation Configuration

Execution with Timeout

Uses Executors.newSingleThreadExecutor() with a 300-second timeout via Future.get(300, SECONDS). On timeout, cancels the future, logs the error, and sets scriptExecutionResult.exception. The executor is always shut down in finally.

Variable Binding

Populates a KotlinScriptContext with all variables and parameters, which the KotlinScriptUtils.appendBlockAfterImports then generates Kotlin property declarations for.

Standard Imports

Adds Kotlin-specific imports beyond the base STANDARD_IMPORTS: localization functions (translate, translateMsg), number formatting extensions (format, formatCurrency, formatBytes), and PfCaches.initialize.
