Hi @JoshuaChen thanks for your report. I have not seen that specific failure, we had reports of troubles with fat jars before, e.g. oracle/graaljs#125 or oracle/graaljs#135 Can you please check if this might be similar? Best, |

I also have exact similar situation as mentioned by @JoshuaChen , instead of unknown source , i got java.nio.file.FileSystemNotFoundException: null |

I have further debugged issue of Jar and found issue with following jar |

Yes, the issue is probably that the path to the We have the exact same issue with a Spring Boot application. |

I'm facing a similar issue. Spring Boot Application works ok when started from IDE, but once I package application and run inside docker (openjdk:8u111-jdk-alpine) I get FileSystemNotFoundException see error log below. @chumer based on your comment on oracle/graaljs#125, please when can we expect a fix on this issue? springBootVersion: 2.1.5.RELEASE graalVersion: 19.0.0 Dependencies: graal-sdk, truffle-api, js, js-scriptengine java.nio.file.FileSystemNotFoundException: null |

Hi all, @pszalanski @chineduekwunife I'm facing the same problem on Springboot, in my case, using JS-19.1.1. @JoshuaChen I actually tried the "classpath" approach and unfortunately it did not work. I got this error I also tried the approach mentioned here but I didn't success. It runs in my IDE but as soon as I generate the jar, run it and the application hits the GraalJS code, the java.nio.file.FileSystemNotFoundException: null is thrown. In case it is relevant, I created a tiny poc using springboot and GraalJS libraries here, I'm using OpenSDK11. |

@tzezula does that also mean your suggested new workaround would not work until using 19.3? |
|
@tzezula What is the current workaround code in order to get this running with 19.3.0? Where is |

@xarfai workaround helped me find the solution (thank you!). Debugged and found out in Just provide the string try {
URL res = com.oracle.js.parser.ScriptEnvironment.class.getClassLoader().getResource("/com/oracle/truffle/js/lang/JavaScriptLanguage.class");
// initialize the file system for the language file
FileSystems.newFileSystem(res.toURI(), new HashMap<>());
} catch (Throwable ignored) {
// in case of starting without fat jar
}Otherwise I was in the same boat and had to downgrade my graalvm dependencies to |

This didn't work for me I verified my class is here JavaScriptLanguage.class Added the above code and still get

I add graal libs in my project to execute JavaScript in Java. My project worked on spingboot framework.
Java Jdk: 9.0.4
spingboot: 2.1.5.RELEASE
graalvm.version : 19.0.0
If I run my project with IDEA directly, graal init success and work fine;
If I buid my project to a fat jar, which contains all libs in it, graal init failed and throw a FileSystemNotFoundException.
