private void doTestBug56179(int parenthesesCount, String innerExpr) {
    ExpressionFactory factory = ExpressionFactory.newInstance();
    ELContext context = new ELContextImpl(factory);
    ValueExpression var = factory.createValueExpression(Boolean.TRUE, Boolean.class);
    context.getVariableMapper().setVariable("test", var);
    StringBuilder expr = new StringBuilder();
    expr.append("${");
    for (int i = 0; i < parenthesesCount; i++) {
        expr.append("(");
    }
    expr.append(innerExpr);
    for (int i = 0; i < parenthesesCount; i++) {
        expr.append(")");
    }
    expr.append("}");
    ValueExpression ve = factory.createValueExpression(context, expr.toString(), String.class);
