JDK : JDK1.4.2-b08 - JDK1.4.2-b22
Testbase : Regression-test
Platform[s] : RedHat Linux 2.1 Adv. Server (64bit)
switch/Mode : -server
Falling test[s]:
        java/nio/Buffer/LimitDirectMemory.sh

Regression-test java/nio/Buffer/LimitDirectMemory.sh test fails on JDK1.4.2 (64 bit).

The following table summarizes the test behaviour with both 32 and 64 JDK1.4.2 java versions
on RedHat Linux 2.1 Adv. Server (64 bit, itanium):

---------------------------------------------------------------------
build 64 bit (ia64) | 32 bit (i586)
---------------------------------------------------------------------
b05 failed (-XX:MaxDirectMemorySize is not implemented)
......................................................................
b06,b07 failed (sun.nio.MaxDirectMemorySize defined)
......................................................................
b08-b22 failed (as described below) | passed
---------------------------------------------------------------------


The first failed testcase is:
runTest -XX:MaxDirectMemorySize=42g -cp ${TESTCLASSES} \
  LimitDirectMemory true 0 ${MAXDEFAULTPLUSONE}

The following comments can be found in LimitDirectMemory.sh:
# A really bad value will be ignored. We will only be able to allocate the default
# amount.

According to these comments the 42g value should be considered senseless and ignored.
But such values are not senseless on 64 bit platforms.
