graal: Discovered unresolved method during parsing: java.nio.ByteBuffer.rewind() #157

Closed serpro69 closed 1 year ago

serpro69 commented 2 years ago 
Error: com.oracle.graal.pointsto.constraints.UnresolvedElementException: Discovered unresolved method during parsing: java.nio.ByteBuffer.rewind(). To diagnose the issue you can use the --allow-incomplete-classpath option. The missing method is then reported at run time when it is accessed the first time.

seems to be caused by a recent jackson version update - https://github.com/serpro69/kotlin-faker/commit/3d5f71ae540b8a3d7e45905b8df568c8ca435263 build run - https://github.com/serpro69/kotlin-faker/actions/runs/3303548647

agentlib does not seem to detect the ByteBuffer usage, hence tried to fix reflect-config.json manually by adding:

  {
    "name": "java.nio.Buffer",
    "methods": [
      {
        "name": "rewind"
      }
    ]
  },
  {
    "name": "java.nio.ByteBuffer",
    "methods": [
      {
        "name": "rewind"
      }
    ]
  },

This causes a different error:

java.nio.ByteBuffer in fact does not contain a rewind method, it's inherited from java.nio.Buffer, hence this looks to be like an issue with graal. Not sure if a later version will fix it, might be worth a try, but as a temporary fix what seems to work is adding an --allow-incomplete-classpath option to graal config. This pushes the problem to runtime, but still seems to be working fine (since we're not calling that part of jackson), so should do as a "temporary" workaround (nothing more permanent than temporary, as they say)
