The dump of the stack trace using Threads.jstack or Threads.jstackStr dump the stack without the first stack of the business class.
For example:
ClassA.methodA call ClassB.methodB
ClassB.methodB call ClassC.methodC
ClassC.methodC call ClassD.methodD
ClassD.methodD is probed and in the probe method print the stack trace with Thrads.jstack
The output show the stack trace from ClassB.methodB
There is a problem with computing the number of stack frames to skip when generating the jstack() output. Please, for the time being use BTraceUtils.jstack() which should yield the correct results.
