             Summary: Infinite or very long hang in CDI builder with Payara embedded maven dep
                 Key: JBIDE-22658
                 URL: https://issues.jboss.org/browse/JBIDE-22658
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: cdi
            Reporter: arjan tijms


In the latest JBoss Tools for Eclipse Mars .2 (would be great if it was easy to see the main version easily, but I guess it's 4.3.1), the CDI builder either infinitely hangs or takes an enormous amount of time (an hour at least on a core M laptop) when payara embedded is present as (test) dependency in a maven project.

During this hang I took a stack trace, which looks as follows:

I debugged Eclipse with a second Eclipse, and it appeared that the code is repeatedly opening {{.m2/repository/fish/payara/extras/payara-embedded-all/4.1.1.162/payara-embedded-all-4.1.1.162.jar}} from {{CDIProject#rebuildBeans}}.

The specific line of code is:

{code:java}
ImplementationCollector ic = new ImplementationCollector(typeDefinitions);
{code}

The number of type definitions it seems to go through in {{ImplementationCollector#process}} is *33009* and the loop looks to be making progress, so it's more likely just incredibly slow and not an infinite hang.

The dependency in pom.xml looks as follows:

{code:xml}
<dependency>
    <groupId>fish.payara.extras</groupId>
    <artifactId>payara-embedded-all</artifactId>
    <version>4.1.1.162</version>
    <scope>test</scope>
</dependency>
{code}
