Description

Name: egR10015			Date: 04/30/2002



Hprof agent shipped with HotSpot 1.4.1-b10 fails to pass the following tests:

nsk/hprof/options/format/format006
nsk/hprof/options/format/format007

from testbase_nsk on all platforms. 

The reason is that HPROF does not support options cpu=times|old and monitor=y
with the option format=b.
I guess, this capability should be implemented in future releases of HPROF, or
at least this issue must be documented. Neither the following public document:

http://java.sun.com/j2se/1.4/docs/guide/jvmpi/jvmpi.html#hprof

nor HPROF itself being run with -Xrunhprof:help say nothing about it.

To reproduce the bug run any program with HPROF as follows:

$ ~/hotspot/jdk1.4.1/solsparc/bin/java -Xrunhprof:cpu=times,format=b HelloWorld
HPROF ERROR: cpu=times|old is not supported with format=b
$ ~/hotspot/jdk1.4.1/solsparc/bin/java -Xrunhprof:cpu=old,format=b HelloWorld
HPROF ERROR: cpu=times|old is not supported with format=b
$ ~/hotspot/jdk1.4.1/solsparc/bin/java -Xrunhprof:monitor=y,format=b HelloWorld
HPROF ERROR: monitor=y is not supported with format=b

EVALUATION ###@###.### 2002-04-30 Re-assigning to jvmpi team. Was originally filed as a runtime bug? If it should be a runtime bug then re-assign and assign me as RE. ###@###.### 2002-09-13 This issue will be resolved by changing the help message to document the limitation that 'format=b' cannot be used with either 'cpu=old' or 'cpu=times'. At this time, adding additional functionality to the sample hprof agent cannot be justified. The following two NSK tests will need to be modified to expect failure instead of success: nsk/hprof/options/format/format006 nsk/hprof/options/format/format007
