JVM crash / fatal error

[edigonzales]

I have a simple pipeline that crashes the jvm

String json = """
{
    "pipeline": [
        {
            "type": "readers.las",
            "filename": "%s"
        },
        {
            "type": "writers.las",
            "filename": "%s",
            "compression": "laszip"
        }
    ]
}
            """.formatted(inputFile, outputFile);    
Pipeline pipeline = new Pipeline(json, LogLevel.Error());
pipeline.execute(); 
pipeline.close();

Error is like:

Error report file is attached. Any idea what goes wrong? I'm on an older Intel Mac running macOS Monterey (12.7.4). Dependencies used are: io.pdal:pdal-native:2.6.2and io.pdal:pdal_3:2.6.2. I installed the pdal binaries and libs with conda. Running PDAL in the terminal works perfectly.

Hi @edigonzales, is there a reproducible example to try?

[edigonzales]

@pomadchin In the zip file, there is the java class and a csv with 2 lines containing urls to a zipped las file. The file will be downloaded, unzipped and then converted to a laz file with pdal. You can run it with jbang:

curl -Ls https://sh.jbang.dev | bash -s - preprocess.java

Hi @edigonzales, the pipeline.initialize() step is missing. The crash happens due to the not initialized pipeline execution.

var pipeline = new Pipeline(json, LogLevel.Error());
pipeline.initialize(); // <- this is the missing piece
pipeline.execute(); 
pipeline.close();

Check the example from the README.md or from the examples project

There is a PR now as well to make initialize private and ensure it's called in the public Pipeline constructor: #94

Thanks!
