Description J Bachorik 2007-04-17 14:46:05 UTC
NetBeans IDE Dev (Build 200704151800)
Linux version 2.6.17-11-generic running on i386
Java HotSpot(TM) Server VM 1.6.0-b105
Bundled Tomcat

Steps to reproduce:
1. Start the TomcatJSPExample application
2. Click "Panel Tag File" "Execute" link
3. Take snapshot
4. Expand the callgraph to the lowest level
5. Select "org.apache.jsp.jsp2.tagfiles.panel_jsp._jspService as a root method
6. Modify profiling
7. Repeat steps 2-4 and notice that those callgraphs are different; the latter
one seems to be trimmed down somehow - it doesn't display the lowest call graph
levels

the user (eg. root methods) i'm lowering the priority to P3
