[jira] [Created] (TOMEE-3933) java.lang.LinkageError on @ViewMap injection
Makkus B. created TOMEE-3933:
--------------------------------
Summary: java.lang.LinkageError on @ViewMap injection
Key: TOMEE-3933
URL: https://issues.apache.org/jira/browse/TOMEE-3933
Project: TomEE
Issue Type: Bug
Components: TomEE Build
Affects Versions: 8.0.11, 8.0.10
Environment: Windows 10, TomEE 8.0.11, JDK 17
Reporter: Makkus B.
I suffer from a LinkageError when loading JSF backing beans that utilize the @ViewMap injection. When referencing the Enroll bean (see below) from JSF I get:
{{{}javax.el.ELException: Fehler beim Lesen von [createNewSession] für den Typ [xrn.portal.ui.Enroll$$OwbNormalScopeProxy0]{}}}{{{}phaseId=RENDER_RESPONSE(6){}}}{{{}Caused by:{}}}
{{java.lang.LinkageError - loader org.apache.tomee.catalina.TomEEWebappClassLoader @eb87c61 attempted duplicate class definition for org.apache.webbeans.custom.Map$$OwbNormalScopeProxy14900025290.

{{Once I remove the reference to @ViewMap in Enroll the error will not occur. }}
{{I'm not so firm in the specs, but I don't think this is an expected behaviour, it it?}}
