    Description

      If you attempt to use java.util.Properties as a normal scoped bean on JDK8 you get the following error:

      Caused by: com.google.common.util.concurrent.ExecutionError: java.lang.IllegalAccessError: tried to access class java.util.Properties$LineReader from class org.jboss.weld.util.Properties$Proxy$_$$_WeldClientProxy
	at com.google.common.cache.LocalCache$Segment.get(LocalCache.java:2201)
	at com.google.common.cache.LocalCache.get(LocalCache.java:3937)

      This is because CDI is proxying the private load0 method which references a package private class. As this class is being defined into a different class loader this type is not accessible and the exception results.

      I think we should not be proxying private methods anyway, I'm not sure why we are doing it at the moment.

          causes

          Bug - A problem that impairs or prevents the functions of the product. JBEAP-3295 Deployment fails with error "java.lang.IllegalAccessError: tried to access class java.util.Properties$LineReader from class org.jboss.weld.util.Properties$Proxy$_$$_WeldClientProxy"

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.

          Bug - A problem that impairs or prevents the functions of the product. WELD-2092 Client proxies should not implement private methods

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
