We’ve got a problem on our solaris machine, as Java takes very long to start. Even on simple things as java -version

>time java -version
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) Server VM (build 16.3-b01, mixed mode)

real    0m34.084s
user    0m0.088s
sys     0m8.331s

Funny enough, this is limited to Java6:

java version "1.5.0_24"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_24-b02)
Java HotSpot(TM) Server VM (build 1.5.0_24-b02, mixed mode)

real    0m0.320s
user    0m0.123s
sys     0m0.138s

Any ideas?

    This is known problem in dtrace initialisation for the jvm. Goes away in java 6u25, I believe, per Sun Alert 1296670.1. We uncovered this problem in an important environment last week, and the pain was excruciating (if you need to run 100 processes a minute, and they abruptly start taking an extra 10s to startup…).

    Workaround if you are pinned to your JVM:

    export DTRACE_DOF_INIT_DISABLE=true

    This has been 100% successful for us, we’re not using the JVM specific dtrace probes anyway.
