Description

XQuery10ExpressionCompilerImpl.getVariableNames(xquery) results in an exception during the parse when the expression ends with a variable reference.

java.lang.StringIndexOutOfBoundsException: String index out of range: 89
at java.lang.String.charAt(String.java:558)

Workaround is to change the expression to have some characters at the end, even if it's just a comment.
