Editor erroneously reports warning in conditional operator

Erroneous warnings are reported in the editor in conditional operators.

Environment

• Operating System: Windows 10 Pro
• JDK version: OpenJDK 11.0.1
• Visual Studio Code version: 1.30.1
• Java extension version: 0.40.0

Steps To Reproduce

Write code like the following:

SpeedController motor;
if (RobotMap.isCompetitionRobot)
{
	motor = new WPI_TalonSRX(RobotMap.liftMotorCanDeviceId);
}
else
{
	motor = new Spark(RobotMap.centerLegMotorPwmChannel);
}
		
motor = RobotMap.isCompetitionRobot
	? new WPI_TalonSRX(RobotMap.liftMotorCanDeviceId)
	: new Spark(RobotMap.centerLegMotorPwmChannel);

where the class Spark extends a class that implements AutoCloseable.

Current Result

No warnings are reported in the if statement. However, the warning:

Resource leak: '<unassigned Closeable value>' is never closed

is reported for the code:

new Spark(RobotMap.centerLegMotorPwmChannel)

in the conditional operator.

Expected Result

No warnings should be reported at all.

Additional Informations

None.

首先，使用 issue 中的条件运算符示例复现该警告，并尽可能使用所列出的 Windows、JDK、VS Code 和 Java extension 版本。跟踪 Java extension 针对条件表达式的资源泄漏分析。完成的标准是：条件表达式不再产生错误警告，同时现有 if 语句的行为保持不变。
