I have the git pull working for fetching a particular revision of nfkc.txt and
the like. Now TestICUFoldingFilterFactory fails tests. Here's what I could find
on that topic:
org.apache.lucene.analysis.icu.ICUFoldingFilter
public static final Normalizer2 NORMALIZER = Normalizer2.getInstance(
// TODO: if the wrong version of the ICU jar is used, loading these data
files may give a strange error.
// maybe add an explicit check?
http://icu-project.org/apiref/icu4j/com/ibm/icu/util/VersionInfo.html
ICUFoldingFilter.class.getResourceAsStream("utr30.nrm"),
"utr30", Normalizer2.Mode.COMPOSE);
eventually calls:
com.ibm.icu.impl.Normalizer2Impl
public Normalizer2Impl load(ByteBuffer bytes) {
try {
this.dataVersion = ICUBinary.readHeaderAndDataVersion(bytes, 1316121906,
IS_ACCEPTABLE);
which throws
Caused by: com.ibm.icu.util.ICUUncheckedIOException: java.io.IOException: ICU
data file error: Header authentication failed, please check if you have a valid
ICU data file; data format 4e726d32, format version 4.0.0.0
0x4e726d32==1316121906, so the data format looks ok to my uninformed eye.
The jar file I have for icu is: icu4j-62.1.jar
I looked at the nfc* files that are now fetched from github and at least
./lucene/analysis/icu/src/data/utr30/nfc.txt is identical.
I’ll get back to this later this afternoon, meanwhile any pointers?
