[11u] Test failing since downport of 8234011: (zipfs) Memory leak in ZipFileSystem.releaseDeflater() was downported

[Lindenmaier, Goetz]

Hi,

We see test jdk/nio/zipfs/ReleaseDeflater.java failing on Windows 64-bit since
"8234011: (zipfs) Memory leak in ZipFileSystem.releaseDeflater()" was downported.

java.lang.IllegalArgumentException: Illegal character in opaque part at index 11: jar:file:C:\\jvmtests\\output_ ....  \\jdk\\nio\\zipfs\\ReleaseDeflater\\ReleaseDeflaterTest.zip
	at java.base/java.net.URI.create(URI.java:883)
	at ReleaseDeflater.main(ReleaseDeflater.java:51)
	at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
	at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)

https://bugs.openjdk.java.net/browse/JDK-8234011
https://hg.openjdk.java.net/jdk-updates/jdk11u-dev/rev/cb299db4a569

I would assume this is a problem with the test, looking at the change.
Does someone have an idea how to fix this?

Best regards,
  Goetz.
