dm-server 2.0.0.M4

I downloaded a fresh copy of version M4 of the server. Then I started it with startup.bat -clean. In serviceability\logs\dm-server, log.txt shows the following:

Is it common to see errors like this on a fresh copy of the server?

Firstly, please note that 2.0.0.M5 is now out, so you may wish to skip M4.

Secondly, those messages look like they emanate from the JVM. They are mostly related to the JVM's Garbage Collector. Which JVM are you using? You should make sure you are using the Sun Java 6 JRE or JDK/SDK when running dm Server v2.

Thanks. I was using jdk 1.6.

[Glyn Normington]

I am not sure which vendor produced your jdk 1.6, but if it was Sun, then those messages are not normal and you should probably look into your Java environment carefully. The messages do not seem to be provoked by dm Server.

I am using Sun's sdk. I didn't encounter this problem in M5.
I ran M4 on two machines - Windows XP and Windows Vista using Sun's sdk. Both exhibited similar behavior.

[Glyn Normington]

M4 logs some of the JVM's MBean events, but M5 doesn't do that. So the JVM is probably functioning normally and the diagnostics in M4 are simply misleading.
