Unable to parse SQL due to reflective access issue with Java modules (java.lang.reflect)

[lefeng872]

Hi, I'm trying to run the parser on the example.sql file using the following command:

java -jar --enable-preview target/qed-parser-1.0-SNAPSHOT-jar-with-dependencies.jar example.sql

However, I encounter the following output and error:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
In file:
        example.sql
java.lang.Exception: In statement:
        declare scalar function fund(varchar) returns float
Unable to make java.lang.reflect.Method(java.lang.Class,java.lang.String,java.lang.Class[],java.lang.Class,java.lang.Class[],int,int,java.lang.String,byte[],byte[],byte[]) accessible: module java.base does not "opens java.lang.reflect" to unnamed module @228575c0

It seems like this issue is related to Java's module system preventing reflective access to internal APIs. I'm using:
Java version: openjdk 19.0.2

System: (e.g., Ubuntu 20.04, x86_64)

Thanks in advance for any help!

Probably you need some extra flags:

parser/flake.nix

Line 23 in 7e7b559

makeWrapper ${pkgs.jre}/bin/java $out/bin/qed-parser --add-flags "--enable-preview --add-opens=java.base/java.lang.reflect=ALL-UNNAMED -jar $jar"
