Hi Mark,

Can you confirm fix for :
* b153 - JDK-8163449 : Allow per protocol setting for URLConnection
defaultUseCaches
Sorry for the delayed reply. I needed to re-create my Java 9 test
environment and it took me a couple of attempts to get it right.
I'm afraid that the current fix is not sufficient for JARUrlConnection.
The problem is that sun.net.www.protocol.jar.JarURLConnection passes
all of the [g|s]et[Default]UseCaches() method calls to the wrapped
URLConnection which is an instance of FileURLConnection. This means
any attempt to control caching for just JAR URLs fails. "jar" always
ends up being treated like "file" which is exactly the case we are
trying to avoid. We want "file" to cache for performance but we don't
want "jar" to cache so we can avoid the associated file locking issues.
Simple test here:
https://github.com/markt-asf/memory-leaks/blob/master/src/org/apache/markt/leaks/net/TestJava9CacheFix.java
Output should be:
true
true
false
false
