A DESCRIPTION OF THE PROBLEM :
This is a duplicate of https://bugs.openjdk.java.net/browse/JDK-8184940 which has only been fixed in JDK 10. Can this fix be back-ported to the JDK-9 branch as well?

If you try to use a jar file that has invalid dates in it then the compiler will fail with the following error:

```
An exception has occurred in the compiler (9.0.1). Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates.

REGRESSION. Last worked in version 8u144

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
If you download a jar that has invalid dates and put it on the classpath then you will get the error.

e.g.

> curl -O http://central.maven.org/maven2/org/apache/beam/beam-sdks-java-core/2.2.0/beam-sdks-java-core-2.2.0.jar

> javac -cp beam-sdks-java-core-2.2.0.jar HelloWorld.java

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
In JDK 8 javac is able to load classes from a jar file with invalid modified dates
ACTUAL -
> javac -cp beam-sdks-java-core-2.2.0.jar HelloWorld.java

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
I'm not sure there is a simple work around except to un-jar the broken jar file and re-jar with valid modified dates.
