[jira] [Commented] (LUCENE-3937) Workaround the XERCES-J bug in
Benchmark
[ https://issues.apache.org/jira/browse/LUCENE-3937?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13241438#comment-13241438 ]
Michael McCandless commented on LUCENE-3937:
--------------------------------------------
LUCENE-1591 is when we first tripped on the XERCESJ-1257 bug... and the bug also happens on enwiki-20110115-pages-articles.xml.bz2 export.
Great idea to workaround Xercesj's bug by using the JVM to decode UTF8, instead of Xercesj...
I'll test this patch now!

> In becnhmark we have a patched version of XERCES which is hard to compile from source. When looking at the code part patched and the source of EnwikiContentSource, to simply provide the XML parser a Reader instead of InputStream, so the broken code is not triggered. This assumes, that the XML-file is always UTF-8.... If not it will no longer work (because the XML parser cannot switch encoding, if it only has a Reader).
