ECJ incorrectly accepts code with potentially uninitialized variable

Javac Version:

javac 1.8.0_451

```

Description:
We have identified a test program rejected by javac but accepted by ECJ. This happens in JDK 8, 11, 17, and 21.
However, the program is invalid as it has a variable might not be initialized.

Test program:
```java
public class Test {
public static void main(String[] strArr) {
while (true) {
if (true)
break;
try {
java.lang.reflect.Method cloneMethod;
try {
cloneMethod = Object.class.getMethod("clone");
} catch (NoSuchMethodException e) {
}
Object obj = new Object();
try {
Object clonedObj = (Object) cloneMethod.invoke(obj);
} catch (Exception e) {
}
} catch (ArithmeticException a_e) {
}

}
}
}
```

Using javac it will have an error:
```bash
javac Test.java
Test.java:15: error: variable cloneMethod might not have been initialized
Object clonedObj = (Object) cloneMethod.invoke(obj);
^
1 error
```

However, using ECJ it will be compiled successfully.

```bash
java -jar ecj-4.36M3.jar --release 21 -d . Test.java
# No error
```

Expected behavior: ECJ should report same error as javac.
Actual behavior: ECJ incorrectly accepts the program.
