JDWP command EventRequest.ClearAllBreakpoints returns unknown error

The following testbase_nsk JDWP tests

    nsk/jdwp/EventRequest/ClearAllBreakpoints/clrallbreakp002
    nsk/jdwp/EventRequest/ClearAllBreakpoints/clrallbreakp003

failed against JDK 1.4.0-rc1-b89 on all platforms except Windows.

These tests exercise JDWP EventRequest.ClearAllBreakpoints command
when no active breakpoint event requests exist.

The JDWP spec for this command says:

    ClearAllBreakpoints Command (3)

        Removes all set breakpoints.

    Out Data
    (None)

    Reply Data
    (None)

    Error Data
    VM_DEAD The virtual machine is not running.

Both tests try to send command packet with this command while no
active breakpoint requests exists. The first test (clrallbreakp002)
does not make any request at all and the second test (clrallbreakp003)
removes all existing breakpoint requests just before sending the
command. In both cases a reply packet with error code is received
from debuggee. Particular error code depends on the test platform:

    Platform Error code
    --------------------------------
    Linux/i386 8
    Solaris/x86 2816
    Solaris/sparc 32-bit 27224
    Solaris/sparc 64-bit 14336
    Windows no error

None of these error codes is documented in the JPDA spec.

Following is citation from the test log (on Solaris/sparc 32-bit):

Please note that another test (clrallbreakp001 test), checking
the same command with existing active breakpoint request, passes.

These tests will appear in the next release of testbase_nsk
located here:

    /net/sqesvr.sfbay/export/vsn/VM/testbase/testbase_nsk.v14

To reproduce the bug run 'doit.sh' script located here:

Use:
    sh doit.sh $JAVA_HOME
Where:
    $JAVA_HOME: points to JDK 1.4-b89
