error "EL1041E" on nested property

[ZeeD]

Hi.
hi have this property:

properties = {k1: {'v11'}, k2: {'v21', 'v22'}, k3: {}}

and I want to retrieve it as

@Value("#{ ${properties} }")
Map<String, List<String>> properties;

I have the error

EL1041E: After parsing a valid expression, there is still more data in the expression: 'lcurly({)'

using Eclipse Version: 2020-09 RC1 (4.17.0 RC1) + Spring Tool Suite 4 Main Feature 4.7.2.202009021121-RELEASE

but on previous version of the ide (and in my code) was not an error

This is a duplicate of #529 and fixed in the upcoming version 4.8.0. In the meantime, you can turn off the SpEL expression validation, as described in the mentioned issue.
