> The attached trivial applications consists of 'test.jsp' and 'WEB-INF/bug.tld' files. The latter includes only one function mapped from the standard Java library. It is not relevant what it does, only that it is mapped. File 'test.jsp' contains this expession:
> ${{}; bug:dummy()}
> Please note that without '{};' (if it is removed or e.g. replaced with '1;) it works correctly, printing something like 'java.lang.Runtime at ...'. (In my real application this is 'my:function1 ({ x: y }) && my:function2 (...)'. Lookup of the first function succeeds, but lookup of the second one fails. If I replace map literal with something else, expression is compiled just fine.)
> However, if expression contains set (or map) literal, JSP compiler fails with this exception:
