Spock does not work in tr_TR locale: Unrecognized block label: given @ line 31, column 13.

[vlsi]

Describe the bug

Spock fails with tr_TR locale:

D:\a\jmeter\jmeter\src\core\src\test\groovy\org\apache\jmeter\engine\util\FunctionParserSpec.groovy: 31: Unrecognized block label: given @ line 31, column 13.
               CompoundVariable.functions.put('__func', Func.class)
               ^

It blocks JMeter testing :-/
apache/jmeter#693

Reason:
Spock uses .toLowerCase() for BlockParseInfo:

spock/spock-core/src/main/java/org/spockframework/compiler/model/BlockParseInfo.java

Lines 139 to 141 in 3ebb5d3

	public String toString() {
	return super.toString().toLowerCase();
	}

The lookup fails here:

spock/spock-core/src/main/java/org/spockframework/compiler/SpecParser.java

Lines 212 to 225 in 3ebb5d3

	if (!label.equals(blockInfo.toString())) continue;
	checkIsValidSuccessor(method, blockInfo, stat.getLineNumber(), stat.getColumnNumber());
	Block block = blockInfo.addNewBlock(method);
	String description = getDescription(stat);
	if (description == null)
	block.getAst().add(stat);
	else
	block.getDescriptions().add(description);
	return block;
	}
	throw new InvalidSpecCompileException(stat, "Unrecognized block label: " + label);

Sample code in question (I believe it does not matter):

import org.apache.jmeter.functions.Function
import org.apache.jmeter.samplers.SampleResult
import org.apache.jmeter.samplers.Sampler

import spock.lang.Specification
import spock.lang.Unroll

@Unroll
class FunctionParserSpec extends Specification {
    def "function '#value' gets compiled"() {
        given:
            CompoundVariable.functions.put('__func', Func.class)
            def parser = new FunctionParser()
        when:
            def result = parser.compileString(value)
        then:
            "$result" == "$expected"
        where:
            value           | expected
            '${__func()}'   | [new Func()]
            '${ __func()}'  | [new Func()]
            '${__func() }'  | [new Func()]
            '${ __func() }' | [new Func()]
    }

To Reproduce

run any Spock test with -Duser.country=TR -Duser.language=tr

Expected behavior

tr_TR should be supported

Actual behavior

Unrecognized block label: given @ line 31, column 13
