I can't recreate the UnixFileTest test failure (I'm running with the IBM
Java 6 VME):
[junit] Running org.apache.harmony.luni.tests.java.io.UnixFileTest
   [junit] Tests run: 1, Failures: 0, Errors: 0, Time elapsed: 0.503 sec
UnixFileTest is not stable for me, it failed intermittently, suppose not
related  to this issue.

What Linux derivation are you running? I'm running Ubuntu 9.04 x86 and

I'm running on Ubuntu 8.04.2. When it failed, I got message similar as yours:

test_getCanonicalPath	Failure	null expected:<...ild/test/luni/folder[1/folder]2> 
but was:<...ild/test/luni/folder[]2>

junit.framework.ComparisonFailure: null 
expected:<...ild/test/luni/folder[1/folder]2> but was:<...ild/test/luni/folder[]2>
at 
org.apache.harmony.luni.tests.java.io.UnixFileTest.test_getCanonicalPath(UnixFileTest.java:50)
at java.lang.reflect.VMReflection.invokeMethod(VMReflection.java)


LUNI tests on trunk consistently pass for me. When I apply this patch,
UnixFileTest fails every time.

Building in release mode (the default for building Harmony  Select) will
currently fail on gcc version 4.3.3 as warnings are treated as errors and
that compiler version is more strict in regards to things like not
checking
return codes of library functions.  The files affected are:
    [exec] hyfiletext.c:234: warning: ignoring return value of 'wctomb',
declared with attribute warn_unused_result
    [exec] hyosdump.c:86: warning: ignoring return value of 'chdir',
declared with attribute warn_unused_result
    [exec] linux/../hysl.c:306: warning: ignoring return value of
'mbtowc', declared with attribute warn_unused_result
    [exec] procimpl.c:176: warning: ignoring return value of 'write',
