I have bundled Logstash within my Java application and launch it using JRuby. It worked fine until upgrading to Java 17. After upgrading, the pipeline fails to start with following exception : > | java.lang.IllegalAccessError: class com.google.googlejavaformat.java.JavaInput (in unnamed module @0x7df34a68) cannot access class com.sun.tools.javac.parser.Tokens$TokenKind (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.parser to unnamed module @0x7df34a68Thu 05 25 14:48:24:925 UTC 2023 | at com.google.googlejavaformat.java.JavaInput.buildToks(com/google/googlejavaformat/java/JavaInput.java:349) | > | --- | --- | > | Thu 05 25 14:48:24:925 UTC 2023 | at com.google.googlejavaformat.java.JavaInput.buildToks(com/google/googlejavaformat/java/JavaInput.java:334) | > | Thu 05 25 14:48:24:925 UTC 2023 | at com.google.googlejavaformat.java.JavaInput.(com/google/googlejavaformat/java/JavaInput.java:276) | > | Thu 05 25 14:48:24:925 UTC 2023 | at com.google.googlejavaformat.java.Formatter.getFormatReplacements(com/google/googlejavaformat/java/Formatter.java:260) | > | Thu 05 25 14:48:24:925 UTC 2023 | at com.google.googlejavaformat.java.Formatter.formatSource(com/google/googlejavaformat/java/Formatter.java:247) | > | Thu 05 25 14:48:24:925 UTC 2023 | at com.google.googlejavaformat.java.Formatter.formatSource(com/google/googlejavaformat/java/Formatter.java:213) | > | Thu 05 25 14:48:24:925 UTC 2023 | at org.logstash.config.ir.compiler.ComputeStepSyntaxElement.generateCode(org/logstash/config/ir/compiler/ComputeStepSyntaxElement.java:174) | > | Thu 05 25 14:48:24:925 UTC 2023 | at org.logstash.config.ir.compiler.ComputeStepSyntaxElement.(org/logstash/config/ir/compiler/ComputeStepSyntaxElement.java:118) | > | Thu 05 25 14:48:24:925 UTC 2023 | at org.logstash.config.ir.compiler.ComputeStepSyntaxElement.create(org/logstash/config/ir/compiler/ComputeStepSyntaxElement.java:89) | I added JVM options **--add-exports** in the jvm.options file within config based on the recommendation here : [[Java17] Add `--add-export` settings to restore JDK17 compatibility by robbavey · Pull Request #13825 · elastic/logstash · GitHub](https://github.com/elastic/logstash/pull/13825) ![image](https://us1.discourse-cdn.com/elastic/original/3X/0/9/09a4d27ac74103cf2a2a245443e9dcd062f2c476.png) Although the error is still not resolved. Any help would be appreciated. ---

[This](https://github.com/google/google-java-format/issues/787) issue has a larger set of add-exports/add-opens options that are used to fix this in a different app. ---
