the error looks related to the bytecode verifier.<br>

Hi Li,<br>
<br>
please try to exclude java.lang.Object from instrumentation, by adding java.lang.Object.*" to the exclusion list.<br>
Does it solve the problem? If not, could you please post a stack trace?<br>
<br>
Thanks,<br>
Andrea<br>

Dear Community<br>
<br>
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.<br>
Is it for DiSl instrumentation only? Does it provide access to user-defined instrumentation?<br>
<br>
Cheers<br>
Li<br>
