[TAP5-1605] Template parsing of expansions can't handle map expressions - ASF JIRA

5.3 introduced map support into the property expression language in the form:

{'foo': 'bar'}

Expansion parsing chokes on the syntax, however. It uses a reluctant regular expression to find the closing brace:

private static final Pattern EXPANSION_PATTERN = Pattern.compile("\\$

{\\s*(.*?)\\s*}

");

Which means that the use of a map inside an expansion prematurely terminates the exansion:

${echoMap(

{"foo": "bar"}

)}

The regex finds the first } and the expression evaluates as:

echoMap({"foo": "bar"

Which is clearly incorrect.
