Hi @saver123sc 
Does the problem exist in 1.6.2?

Could you check your jre for `long com.ibm.lang.management.OperatingSystemMXBean.getProcessCpuTimeByNS()` method? 
It should be there as per the [documentation]( https://www.ibm.com/support/knowledgecenter/en/SSYKE2_6.0.0/com.ibm.java.api.60.doc/com.ibm.lang.management/com/ibm/lang/management/OperatingSystemMXBean.html).

Could you also post your agent log so we can take a look at it? (The log file is located under *$PINPOINT_AGENT/log* directory).

In the mean time, you could also try setting `profiler.jvm.vendor.name=oracle` in *pinpoint.config* and see if that works.
Thanks. @Xylus 

Thank you,Problems on websphere7, I have solved it by reshipment wesphere
 Glad to hear you worked it out :+1:  > @Xylus

I also get this problem. And how to solve it. @chuanyi-fang I think some versions of ibm java 7 does not have the method above, causing startup failure.
The issue will be fixed next version.

In the mean time, please try downloading the jdk 7 from the ibm website and try again.
Please check #4585 for more detail. I have found the method in the "jlm.jar" of WAS's "jre.pak".And solved now.

 resolved via #4694 
pinpoint start failed.
After deploymented  agent1.70 ，the following error after start the websphere server:
