Package dev.frostlake.executor.udf

Class TruffleLogBridge

java.lang.Object

java.util.logging.Handler

dev.frostlake.executor.udf.TruffleLogBridge

public final class TruffleLogBridge
extends Handler

Routes Truffle/polyglot log output into SLF4J — the "configure logging using the polyglot embedding API" option: installed as the engine log handler, so GraalVM's warnings and diagnostics land in the engine log (with per-language logger names under the polyglot. prefix) instead of being printed to stderr.

installOn(Engine.Builder) respects the documented host-launcher override: when -Dpolyglot.log.file=<path> is set, no handler is installed and the polyglot runtime writes to that file itself.
