failing test (on jruby): css search problem involving whitespace and …

[jkraemer]

…node removal

The problem seems to occur only when due to removal of a node surrounded by whitespace two consecutive text nodes are left behind. In that case a css search for the remaining element ends up in a DTM exception:

Java::JavaLang::RuntimeException: Could not resolve the node to a handle
   org.apache.xml.dtm.ref.DTMManagerDefault.getDTMHandleFromNode(DTMManagerDefault.java:576)
    org.apache.xpath.XPathContext.getDTMHandleFromNode(XPathContext.java:184)       
    org.apache.xpath.XPath.execute(XPath.java:303) 
    nokogiri.XmlXpathContext.tryGetNodeSet(XmlXpathContext.java:198)
...

Since it might have been related I already tried replacing all uses of internal com.sun API with the official Xalan API, adding the 2.7.2 Xalan jars as per #1212, but it didn't help with this problem (and still caused the same errors mentioned there).

What is status? flavorjones/loofah#88 (comment) says this is Rails 4.2 with JRuby.

As I wrote at flavorjones/loofah#94 (comment), I cannot understand loofah and nokogiri support policy.

[flavorjones]

Looking at this now.

@kares If you are looking for important JRuby work, this issue is currently blocking Loofah and Rails on JRuby.

I've pushed the branch 1320_jkraemer_jruby-css-search-crash with the above failing test.

seems like a xalan bug to me - not sure about the 'best' work-around (since Xalan is no longer maintained).
might take me quite some time to get right - no promises that a fix will land (although do believe its fixable)
