#986 NPE calling overloaded extension function in saxon:evaluate
A NullPointerException occurs if the XPath expression supplied as an argument to saxon:evaluate() (or saxon:expression()) contains a call on a Java extension function that maps to an overloaded Java method. For example:
<xsl:value-of select="saxon:evaluate('Math:abs(-1)') xmlns:Math=" java:java.lang.Math"=""/>
A patch (to module JavaExtensionLibrary) is being added to Subversion on the 9.1 and 9.2 branches. The same code is also present in DotNetExtensionLibrary and the same fix is being applied there. Only the Java version has been tested. Test case added to Saxon XSLT test suite: evaluate027.
Fixed in 9.2.0.3 and in 9.1.0.8
