[DiSL-user] Instrument all classes

[Sui, Li]

Hi Andrea


I added java.lang Object* to the exclusion list. I used the "smoke" example and change to scope="*"

Subject: Re: [DiSL-user] Instrument all classes

Hi Li,

please try to exclude java.lang.Object from instrumentation, by adding “java.lang.Object.*" to the exclusion list.
Does it solve the problem? If not, could you please post a stack trace?

Thanks,
Andrea

Dear Community

Does DiSl allow to instrument all classes? (application+ JRE core)?  I tried scope = "*"  and JVM crashed. I think DiSl has this dynamic bypass mechanismwhich instruments classes in different JVM.
Is it for DiSl instrumentation only? Does it provide access to user-defined instrumentation?

Cheers
Li
