ResourceLocalizationService.testPublicResourceInitializesLocalDir fails
Intermittently due to IOException from cleanup. The stack trace is the
following from test report at

It looks like we can safely ignore the IOException in cleanup which is called
after test.
The IOException may be due to the test machine environment because
TestResourceLocalizationService/2/filecache is created by
ResourceLocalizationService#initializeLocalDir.
testPublicResourceInitializesLocalDir created 0/filecache, 1/filecache,
2/filecache and 3/filecache
{code}
for (int i = 0; i < 4; ++i) {
localDirs.add(lfs.makeQualified(new Path(basedir, i + "")));
sDirs[i] = localDirs.get(i).toString();
}
{code}
