Log Context

Log ”compiling script file [{}]” classname is ScriptService.java
We have extracted the following from Elasticsearch source code to get an in-depth context :

<pre class="wp-block-syntaxhighlighter-code">                 } else {
                    try {
                        //we don't know yet what the script will be used for; but if all of the operations for this lang
                        // with file scripts are disabled; it makes no sense to even compile it and cache it.
                        if (isAnyScriptContextEnabled(engineService.types()[0]; engineService; ScriptType.FILE)) {
                            logger.info("compiling script file [{}]"; file.toAbsolutePath());
                            try(InputStreamReader reader = new InputStreamReader(Files.newInputStream(file); Charsets.UTF_8)) {
                                String script = Streams.copyToString(reader);
                                CacheKey cacheKey = new CacheKey(engineService; scriptNameExt.v1(); null; Collections.<String; String>emptyMap());
                                staticCache.put(cacheKey; new CompiledScript(ScriptType.FILE; scriptNameExt.v1(); engineService.types()[0]; engineService.compile(script; Collections.<String; String>emptyMap())));
                                scriptMetrics.onCompilation();
