Odd class format error #23727

fwgreen · 2022-02-15T14:13:19Z

Describe the bug

Only The LicensedPracticalNurse class triggers this error at startup while the other classes work fine (removing it fixes the problem). The snippet below is the entire application.

@Path("/api/list")
class ReactiveGreetingResource {

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Path("/lpn")
    fun lpn() = LicensedPracticalNurse.listAll()

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Path("/all")
    fun all() = NursingStaffMember.listAll()

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Path("/rn")
    fun rn() = RegisteredNurse.listAll()

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Path("/cna")
    fun cna() = CertifiedNursingAssisant.listAll()
}

enum class JobTitle {
    CNA, RN , LPN
}

@MappedSuperclass
abstract class AbstractStaffMember : PanacheEntity() {
    @Column(name = "staff_id")
    lateinit var staffId: String
    @Column(name = "first_name")
    lateinit var firstName: String
    @Column(name = "last_name")
    lateinit var lastName: String
    @Column(name = "full_name")
    lateinit var fullName: String
    @Enumerated(EnumType.STRING)
    @Column(name = "job_title")
    lateinit var jobTitle: JobTitle
}

@Entity
@Table(name = "LICENSED_PRACTICAL_NURSE")
class LicensedPracticalNurse : AbstractStaffMember() {
    companion object :  PanacheCompanion<LicensedPracticalNurse>
}

@Entity
@Table(name = "REGISTERED_NURSE")
class RegisteredNurse : AbstractStaffMember() {
    companion object :  PanacheCompanion<RegisteredNurse>
}

@Entity
@Table(name = "CERTIFIED_NURSING_ASSISTANT")
class CertifiedNursingAssisant : AbstractStaffMember() {
    companion object :  PanacheCompanion<CertifiedNursingAssisant>
}

Seems like a bug in Panache Kotlin

evanchooly · 2022-02-28T19:34:02Z

I created a new project from the website and copied these classes in. I can't recreate it. Can you provide a project that recreates this, @fwgreen ?

fwgreen · 2022-03-01T00:48:51Z

@evanchooly Thanks for taking the time to investigate. Here's a link https://github.com/fwgreen/code-with-quarkus

evanchooly · 2022-03-02T16:08:46Z

I've isolated the cause if not the precise why: your model classes are packageless and that trips up quarkus somehow. Try adding a package declaration to your source and see if that resolves your issues. I'll dig in to the why on this end.

evanchooly · 2022-03-02T17:11:25Z

the bytecode looks exactly same except for the package related changes, of course. perhaps is a jvm/classloading wrinkle? @dmlloyd ?

fwgreen · 2022-03-02T17:35:09Z

Putting the models in a package does resolve the problem.

dmlloyd · 2022-03-02T18:21:43Z

I think whatever is generating the code is simply generating an invalid signature, or rather one not accepted by the JVM class verifier. The signature is a piece of data used to establish the generic type of the class (as opposed to the descriptor, which is used to unambiguously identify a class or member). The relevant info can be found in §4.7.9 of the JVM specification version 17. I believe the expected signature string in this case would be LLicensedPracticalNurse$Companion; (note the leading L and trailing ;).

evanchooly · 2022-03-03T00:07:59Z

ah ha! i think i've found the errant entry (I was looking at the wrong/pretransformation .class files):

    LOCALVARIABLE this LicensedPracticalNurse$Companion L0 L1 0

Others have the appropriate LLicensedPracticalNurse$Companion; formulation. It only appears to affect the local vars section which limits the area to investigate at least.
