I'm having problems getting HPROF, and the associated HAT, working
with the latest Panther Java release. When I run a program with
profiling, as in
% java -Xrunhprof:heap=all,depth=200,doe=n,thread=y,format=b -verbose:gc -Xmx500m -jar ...
I get the following complaints from HPROF:
HPROF ERROR: unable to resolve a method id
HPROF ERROR : got a NULL trace in class_load
HPROF ERROR: class ID already in use
Then, when I attempt to run hat:
% /usr/local/bin/hat java.hprof
Started HTTP server on port 7000
Reading from java.hprof...
java.io.IOException: Unrecognized magic number: 28303885
at hat.parser.Reader.readFile(Reader.java:99)
at hat.Main.main(Main.java:149)
%
Anyone have any ideas?
Bill
