I'm curious, under what circumstances would, before
https://bugs.openjdk.java.net/browse/JDK-8237750, we ever hit the LoadLibrary
in imageDecompressor.cpp? Did this ever work? Was there ever a scenario where
the JVM was not involved and hence the zip.dll was not loaded already?
For me, the code looks good unless I miss a scenario where we don't have the
JVM loaded already at this point.
