Hello,

I cannot seem to find release notes for u14p, the javase performance release.

Thank you but these notes are for u14 not u14p, the performance release that you get from htttp://java.sun.com/performance

My apologies for not being clearer.

u14p: apart from running hotspot vm build 15.0-b07 versus vm 14, I see that the JSE build 1.6.0_14-p-b03

anyone knows the details of this 1.6.0_14-p-b03 versus build 14.0-b16.

I ask a tech guy at Sun I know and his reply was that the features of 14p were basically the same as update 14 except it included some improvements from OpenJDK 6 build 15.

It sounds fairly minor but I found that -XX:DoEscapeAnaylsis was slightly slower (than doing nothing) in update 14 for my code base, but slightly faster for 14p. Not sure if the differences were conclusive....

So the release notes for 14p are the same as 14, but include some last minute improvements. You can look at the change log for OpenJDK, but I didn't see much from that.
