BytecodeParserError: java.lang.NullPointerException: Cannot invoke "jdk.vm.ci.meta.JavaType.toJavaName()" because "type" is null

[eregon]

Describe the issue
This error happens, when using --language:js or --language:ruby.
Without --language:js/--language:ruby it builds fine (and fails at runtime due to the missing language).
Found by @joshlong who wants to embed Ruby in a native image.

Steps to reproduce the issue
Please include both build steps as well as run steps

1. export JAVA_HOME=/path/to/graalvm
2. git clone --branch simplify https://github.com/eregon/truffleruby-embed-spring.git
3. ./native.sh

Describe GraalVM and your environment:

• GraalVM version: 22.3 and dev build
• JDK major version: 17
• OS: Linux
• Architecture: AMD64

[eregon]

FWIW I also tried the same but without SpringBoot on this branch: https://github.com/eregon/truffleruby-embed-spring/tree/without-spring
And that works for both js and ruby.

So somehow the combination Native Image + SpringBoot + GraalVM language seems to cause the above issue.

[oubidar-Abderrahim]

Hi, thanks Benoit, we'll take a look into this shortly

[9yx]

Hi, same error in spring boot when adding --language:js without it application starts
graalvm 22.3.0

plugins {
    id("org.springframework.boot") version "3.0.1"
    id("io.spring.dependency-management") version "1.1.0"
    id("org.graalvm.buildtools.native") version "0.9.19"
}

graalvmNative {
    binaries {
        named("main") {
            buildArgs.add("--language:js")
        }
    }
}

[oubidar-Abderrahim]

Tracked internally on GR 43212

[cstancu]

The problem is that using field value transformers (a feature that Spring relies on) is not working with ParseOnce (a feature that is enabled by default and that Spring also depends on). Since Truffle (used by the --language:js) doesn't currently support ParseOnce, it is disabling it automatically. So combining Spring with a Truffle language is currently not supported. ParseOnce will become the only supported mode as soon as work for Truffle to support it is completed.

[cstancu]

For reasons why Truffle languages are not supported in Spring yet please see #4473. I'm working on a PR to have a better error message.

[cstancu]

This PR #5781 explicitly disables ParseOnce when field value transformers for fields of run time initialized classes are encountered.
