I can confirm the NCDFE. This could be a duplicate of: 7055941: JSR 292 method handle invocation causes excessive deoptimization for types not on boot class path

A recent version of HotSpot runs both Hanois at the same speed. -- Christian On Aug 26, 2011, at 2:00 AM, Mark Roos wrote: > The error I see is that at random times when I am executing Smalltalk on jvm > I get occasional a ClassDefNotFound > during an InvokeExact.
