Flow 24 alpha does not work on payara-micro due to ASM incompatibility

[MarcinVaadin]

Description of the bug

From StackOverflow:

I tried to run Vaadin Flow 24.0.0.alpha7 (because it supports Jakarta EE 9) on Payara Micro but Vaadin servlet didn't deploy.

I believe Payara Micro 6.2022.2 should support it theoretically however when I tried to run it on Java 17 I got multiple errors of this sort:

Exception while visiting com/vaadin/flow/data/provider/SortDirection.class of size 1425 java.lang.UnsupportedOperationException: PermittedSubclasses requires ASM9 When I switched to Java 19 I got the same ASM9 errors plus a bunch of new ones like this:

Exception while visiting WEB-INF/classes/one/esng/ang/ui/views/MainLayout.class of size 3967 java.lang.IllegalArgumentException: Unsupported class file major version 63 Is there any way to make it work?

Expected behavior

Should work

Minimal reproducible example

we should add payara-micro example to one of skeleton starter modules

Versions

• Vaadin / Flow version: 24 alpha8
• Java version: 17
• Application Server (if applicable): payara-micro 6.xx

How about changing the enum to something like this to remove the need of the kinda fancy stuff ;)

public enum SortDirection {

  /**
   * Ascending (e.g. A-Z, 1..9) sort order
   */
  ASCENDING(Constants.ASCENDING_OPPOSITE),

  /**
   * Descending (e.g. Z-A, 9..1) sort order
   */
  DESCENDING(Constants.DESCENDING_OPPOSITE);

  private final SortDirection opposite;

  SortDirection(SortDirection opposite) {
    this.opposite = opposite;
  }

  /**
   * Get the sort direction that is the direct opposite to this one.
   *
   * @return a sort direction value
   */
  public SortDirection getOpposite() {
    return opposite;
  }

  private static class Constants {

    public static final SortDirection ASCENDING_OPPOSITE = DESCENDING;
    public static final SortDirection DESCENDING_OPPOSITE = ASCENDING;
  }
}

Same issue for com/vaadin/flow/component/grid/Grid$SelectionMode.class.

Is there anything for us to do here or should we close this issue and wait for Payara to fix their deps?

[mshabarov]

I suggest first to try change the Flow codes for SortDirection, ComponentTracker$Location and Grid$SelectionMode and see if there Payara would start then.

Example to reproduce https://github.com/vaadin/skeleton-starter-flow-cdi/tree/v24-payara : mvn clean package payara-micro:start

[mshabarov]

Tested the above starter with patched Flow https://github.com/vaadin/flow/tree/flow-payara and Flow Grid https://github.com/vaadin/flow-components/tree/grid-payara I got basically only one error:

[2023-01-24T19:25:42.714+0200] [] [SEVERE] [] [javax.enterprise.system.tools.deployment.common] [tid: _ThreadID=1 _ThreadName=main] [timeMillis: 1674581142714] [levelValue: 1000] Exception while visiting sun.security.util.KnownOIDs

and a blank page:

No errors in the browser console or network tab. Will set a verbose logging level for the server and see.

The problem seems to be that MainView is not considered a CDI bean, and thus its @PostConstructor is not invoked, so child components are not added to the view

[mcollovati]

The same happens with wildfly 27 (alpha), so the problem is with Jakarta EE 10 and CDI 4, that changed the default bean discovery mode to annotated, as mentioned in vaadin/cdi#411

[mcollovati]

Just tested against latest Flow and grid modules and the ASM issues seems to be resolved. For the blank page issue I will create a PR on skeleton-starter-flow-cdi repository to add the @CdiComponent to MainView, so it will be detected as a CDI bean and lifecycle hooks will be correctly invoked
