Hello,

I've tried the EAP build a few weeka ago.

I tried to launch it this morning and refused because a newer version is available.
So i downloaded the last release (EAP build 14014) and installed it.

But it tells me the exact same thing (This EAP build has expired).

Is it a normal behaviour ? Or a mistake in the latest build ?

[Anton Katilin]

The problem is fixed now.

Please download the latest build 14016.

I downloaded yjp-2014-eap-build-14022.exe under Windows 7 SP1, but when I run the installer I get an error "Extract: error writing to file tools.jar". Any clues? My installer file size is 42,632 Kb. Java version 1.6.0_26-b03 64 bit. Free space 127Gb on the target disk.

I suspect my problem was the first time I downloaded the jar, it got corrupted and the install failed, probably around the tools.jar extract. The second time I downloaded a valid jar, but I attempted to install it to the default (previous) directory and I got the error above. The solution was to delete the default install directory and start again.

I've downloaded the latest EAP version of YJP (build 14032), successfully installed and started it. But when I launched a demo profiling session and clicked on "detail" pseudo link (near "Threads" title on the CPU tab) I've caught an internal error window with the following stacktrace:

Thank you, Vladimir.
I will be waiting for next build.

Build 14034 with the fix is available for download.

[thyzz]

I've downloaded the newest 2014 EAP, build 14042
I'm encountering 2 issues:

1. I can't attach to a (local)JVM dat doesn't have the agent installed. I get the instructions how to install the agent...
2. After creating a memory snapshot. The snapshot can't be opened. I get the following error:
"
Cannot open snapshot: Dominator computing failed.
...
Detail:
Cannot execute command:
/Application/<..>.app/bin/mac/yjp_dc
/tmp/yjp_dc_<large_number>.dc_input
/Users/<user>/Snapshots/<name.snapshot.idom
snca
"

I'm running a mac 10.9
With java jre version 1.7.0_55 64-bit

Please try the bundle labeled "OS X Tiger (10.4) - OS X Snow Leopard (10.6)":
http://www.yourkit.com/eap/

Does it work?

[thyzz]

Yes
With the OS X Tiger (10.4) - OS X Snow Leopard (10.6) 2014 EAP, build 14044 I can attach to already running processes and it allows me to open the memory snapshots already created!!!

[Anton Katilin]

We have reproduced the problem and are working on it.

[Anton Katilin]

The latest builds of versions 2013 and 2014 EAP fix the issues.
