Hi Lubomir<br>
<br>
I trying to construct a call graph dynamically. The scope of the analysis is Java Class library+application. So I would like to include classes in JDK as many as possible.<br>
I believe the bottom layer of DiSL can fully instrument JDK, is it right? It seems I have to implement something similar to that?<br>
<br>
Cheers<br>
Li<br>

<br>
Hi Li,<br>
<br>
while DiSL can instrument whatever you want, JVM can be quite picky about some<br>
of the classes in the Java Class Library so when using DiSL alone, the<br>
exclusion list may need to be a bit more extensive.<br>
<br>
Can you share a bit of what do you want your instrumentation to do? Chances<br>
are that have tried that before and can help in other ways if not with<br>
debugging, which is not easy to do with the JVM crashing.<br>
<br>
Can you get the instrumentation to work if you instrument your application<br>
only, i.e., limit scope to the application package?<br>
<br>
Only then I would try to slowly extend the scope of the instrumentation, first<br>
excluding packages such as java.lang.*.*, java.security.*.*, sun.misc.*.*,<br>
sun.reflect.*.* and then try reduce exclusion scope.<br>
<br>
<br>
Best regards,<br>
Lubomir<br>
