Robin, Sorry to hear about your problem. I don't know of any similar reports. The fact that your application works with Hotspot disabled means that the problem is a bug in Hotspot. I stopped programming in 2004 so am out of touch with what's happening with Java, but perhaps there's an alternative to Hotspot for compiling Java. When I started VisAD in 1996 it included lots of workarounds for bugs in Java3D. It may be possible to come up with a workaround for this Hotspot bug, but it would be a difficult job. With a compiler bug it may be impossible to get a stack dump of the crash. Best wishes, Bill Hibbard ----- Original Message ----- From: Robin Roos Sent: 02/07/13 04:02 AM To: visad@xxxxxxxxxxxxxxxx Subject: [visad] -XInt Hi Folks I am working with a third-party application for financial analysis. I observe that the application tends to crash when visualizing and rotating a 3D image of a surface, unless the VM arg â-XIntâ is provided. I also observe that the package has dependencies on VisAD (we do not know what version of VisAD is used). -XInt is a VM arg which tells the JVM never to use the HotSpot compiler to compile Java bytecode into machine code. -XInt has obvious performance implications, since all Java bytecode is always interpreted. Without wishing to imply that there are any deficiencies in VisAD itself, has anyone else reported a similar issue (perhaps with earlier versions)? Much obliged, Robin. ------------------------------------------------------------------- This e-mail and attachments may contain confidential, proprietary or legally privileged information.
