quarkus: Quarkus 2.0.1 VerifyError:Bad access to protected data in invokevirtual

Describe the bug

Some of my tests (@QuarkusTest) fail with the following error:

[ERROR] com.ApiTest.method  Time elapsed: 0 s  <<< ERROR!
java.lang.RuntimeException: java.lang.RuntimeException: Failed to start quarkus
Caused by: java.lang.RuntimeException: Failed to start quarkus
Caused by: java.lang.VerifyError:
Bad access to protected data in invokevirtual
Exception Details:
  Location:
    com/company/me/Bean_ClientProxy.isMethod()Z @43: invokevirtual
  Reason:
    Type 'com/company/me/Bean' (current frame, stack[0]) is not assignable to 'com/company/me/Bean_ClientProxy'
  Current Frame:
    bci: @43
    flags: { }
    locals: { 'com/company/me/Bean_ClientProxy', '[Z' }
    stack: { 'com/company/me/Bean' }
  Bytecode:
    ...
    ...
    ...
    
  Stackmap Table:
    append_frame(@14,Object[#610])
    same_frame(@29)

The Bean extends OtherAbstractBean which extends ParentAbstractBean which extends org.apache.camel.builder.RouteBuilder. The method in the error message (Bean_ClientProxy.isMethod) is a protected one and sometimes the test fails with another protected method.

The application seems to work fine, but @QuarkusTest is failing

Expected behavior

No Errors expected

To Reproduce

Unfortunately, I can’t share the code and could not reproduce it in a demo project
