[jira] [Created] (XERCESJ-1752) Cannot use latest IBM ICU with latest Xerces, need support for the latest Eclipse XPath Engine
Ivan Pedruzzi created XERCESJ-1752:
--------------------------------------
Summary: Cannot use latest IBM ICU with latest Xerces, need support for the latest Eclipse XPath Engine
Key: XERCESJ-1752
URL: https://issues.apache.org/jira/browse/XERCESJ-1752
Project: Xerces2-J
Issue Type: Improvement
Reporter: Ivan Pedruzzi
The latest ICU 72 [https://github.com/unicode-org/icu/releases/download/release-72-1/icu4j-72_1.jar]
breaks the Eclipse XPath engine 1.2.1 bundled with Xerces.
the ICU lib removed function isHighSurrogate from class UCharacter which is used by the constructor of class StringCodePointIterator
Exception in thread "main" java.lang.NoSuchMethodError: com.ibm.icu.lang.UCharacter.isHighSurrogate(C)Z
at org.eclipse.wst.xml.xpath2.processor.internal.utils.StringCodePointIterator.<init>(StringCodePointIterator.java:35)
to fix the problem, you may think to update to the latest Eclipse XPath engine 2.1 [https://www.jabylon.org/maven/org/eclipse/wst/xml/xpath2/processor/2.1.100/processor-2.1.100.jar]
but that breaks Xerces 2.1
because Eclipse XPath removed the constructor of class DefaultEvaluator used by AbstractXPath2EngineImpl.evaluateXPathExpr
Exception in thread "main" java.lang.NoSuchMethodError: org.eclipse.wst.xml.xpath2.processor.DefaultEvaluator.<init>(Lorg/eclipse/wst/xml/xpath2/processor/DynamicContext;Lorg/w3c/dom/Document;Lorg/w3c/dom/Node;)V
at org.apache.xerces.impl.xs.AbstractXPath2EngineImpl.evaluateXPathExpr(Unknown Source)
Looking at the new constructor rather than taking a single org.w3c.dom.Node, now takes an array of Objects, it seems that they accept a sequence of items as context
public DefaultEvaluator(
org.eclipse.wst.xml.xpath2.api.StaticContext staticContext,
org.eclipse.wst.xml.xpath2.api.DynamicContext dynamicContext,
Object[] contextItems) {
this(staticContext, dynamicContext);
// initialize context item with root of document
ResultBuffer rs = new ResultBuffer();
for (Object obj : contextItems) {
if (obj instanceof Node) rs.add(NodeType.dom_to_xpath((Node)obj, _sc.getTypeModel()));
}
set_focus(new Focus(rs.getSequence()));
_param = null;
}
