[jboss-jira] [JBoss JIRA] (WFLY-1289) Spurious warnings about invalid META-INF/services class name

[David Lloyd (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-1289?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12770680#comment-12770680 ] 

David Lloyd commented on WFLY-1289:
-----------------------------------

In reality a class name has very few constraints; it is a series of "unqualified names" separated by periods.  The JVM spec §4.2.2 describes unqualified names:

{quote}
An unqualified name must not contain any of the ASCII characters . ; [ / (that is, period or semicolon or left square bracket or forward slash).
{quote}

Other than these, a class name can contain *any* Unicode code point.  So we clearly have some adjustment to do here. :)

> When an application contains a {{META-INF/services}} resource referencing an inner class, JBoss prints a spurious warning
> {noformat}
> JBAS015893: Encountered invalid class name 'com.acme.Foo$Bar' for service type 'com.acme.Service'
> {noformat}
> {{META-INF/services}} lists classes with their binary name, so dollar characters are likely to occur.
> {{org.jboss.as.server.deployment.ServiceLoaderProcessor}} scans all {{META-INF/services}} resources but does not accept dollar characters in its validation pattern. 
> (Note: I can't select any 7.x release for "Affects Version".)
