The attached crash happend when using the standard HotSpot and not the DCE VM. The version string says "Java HotSpot(TM) Server VM" and not "Dynamic Code Evolution 64-Bit Server VM", so it cannot be an issue related to the DCE VM. Most likely the same applies to the first issue (try to increase permanent generation size with for example -XX:MaxPermSize=512m).
Please report bugs of the DCE VM at http://ssw.jku.at/dcevm/bugtracking/ as suggested in the crash dumps of the VM. - thomas On 12/22/2010 09:41 AM, 玄希 wrote: > Hi, the HotSwap.patch is amazing work.
