Summary: ReflectiveAttachmentRefScanner recursively scanning enums
Project: JBoss Web Services
Issue Type: Bug
Security Level: Public (Everyone can see)
Reporter: Simon Berthaiume
Sorry if this isn't a top-notch bug report, I'm really not that familiar with
JBoss and it's modules.
The issue is that when starting JBoss (jboss-5.1.0.GA) with our webservices WAR was taking
us a tremendous amount of time (25+ minutes vs ~5 minutes without) and they contain about
nothing (just a WS to Bean bridge basically). After much investigation, I discovered that
most of the startup time (75%+) was spent in the
method; further investigation revealed that out issues were with Enum types.
Scaning an enum type could be in the O(n^2) order of magnitude as it seems the method will
call itself (recursively) on all values of the enum again and again (up to a point). We
have some fairly large enums here (1000+ elements, could be bad design, but still) and
when the scanner tried to scan them, it could take up to 35 seconds (not ms) for a single
As a workaround I figured-out that adding the @XmlMimeType annotation to enum properties
of classes used in our WS interfaces sort of solved our issues, the startup time went from
25-30 minutes to about 6.5 minutes.
Not sure if this is a bug or a feature, but I though I should let the community know about
this as I have never found any posts regarding that issue.
