    Description

      org.apache.ode.bpel.elang.xpath20.compiler.XPath20ExpressionCompilerImpl.doJaxpCompile(OXPath20ExpressionBPEL20 out, Expression source):Line 169-170
      for (String functionExpr : extractFunctionExprs(xpathStr)) {
      expr = xpe.compile(functionExpr); //Line: 170 here an exception is thrown
      try

      { expr.evaluate(node); }

      catch (XPathExpressionException xpee)

      { // swallow errors caused by uninitialized variable }

      }

      xpathStr equals:
      bpel:doXslTransform("1.0.1/some.xsl", $Variable.body, "someParameter", $OtherVariable.body, "someParameter2", $SwsHeaderRQ, "someParameter3", true(), "someXpathParameter", $XPath)

      The result of extractFunctionExprs(xpathStr) is a list with one element:

      bpel:doXslTransform("1.0.1/some.xsl", $Variable.body, "someParameter", $OtherVariable.body, "someParameter2", $SwsHeaderRQ, "someParameter3", true()

      but it should be the same as xpathStr.

      So the results is that Line 170 throws an exception:

      Caused by: net.sf.saxon.trans.XPathException: XPath syntax error at char 149 in

      {...derRQ, "someParameter3", tru...}:
      expected ")", found "<eof>"

      What is more the application doesn't show a stractrace:

      2010-06-04 11:06:10,254 [Timer-1] DEBUG org.apache.ode.bpel.elang.xpath20.compiler.XPath20ExpressionCompilerBPEL20 - javax.xml.xpath.XPathExpressionException

      because the exception is logged this way:
      __log.debug(e);

      but it should be
      __log.debug("some message", e);


      The exception:
