[news.eclipse.tptp] unknown classes and methods when profiling with Java

[khilan@xxxxxxxxxxxx (Khilan)]

Dear all,

I'm a newbie to TPTP and have run into a problem with unknown classes and 
methods. I'm using Eclipse 3.5 with Java 6 and TPTP 4.6 on Ubuntu Jaunty 
9.04 to profile a simple application:

public static void main(String[] args) {
   System.out.println();
}

I profile this as a Java Application and am performing an Execution Time 
Analysis with "Collect method CPU time information" unchecked and "Show 
execution flow graphical details" checked. Furthermore, I have defined a 
filter "No Filter" which contains the single rule "Classes: *, Methods: *, 
Rule: INCLUDE".

In the profiler output, the following packages appear:
default
java.net
java.nio
java.nio.charset
java.util
sun.jkernel
sun.misc
sun.net.www
sun.net.www.protocol.file
sun.security.provider
sun.security.util

This gives me confidence that the filter is working. However, the java.io 
package doesn't appear and instead there are a number of "unknown" classes 
listed in the default package. Also, when looking at the call tree, there 
are "unknown" methods too, which I'm guessing belong to these unknown 
classes.

I've also tried using Java 5 (with Eclipse 3.5 and TPTP 4.6) but I still 
get the same problem.

Any help would be appreciated,

Thanks,
Khilan
