The following test cases from 1.4.2_libs testsuite failed with jdk1.4.2 on Solaris 10 x86

java_nio/Channel/FileChannel/FCtransferTo
java_nio/Channel/FileChannel/FCtransferTosize

The message is (for example for FCtransferTo) the following:
xferTest01 FAIL: Unexpected Exception
java.io.IOException: Not enough space

java.nio.channels.FileChannel.transferTo() Failed

It doesn't looks like setup issue or testsuite issue because of the test passed with jdk5.0

It is not a regression.
