Hi Per,
While testing different JVMs I realized that it's fixed in openjdk 11,
e.g. openjdk version "11.0.1" 2018-10-16 LTS (zulu build), maybe by this

It sounds reasonable to have that as an option, but I'd like to see it
requested by some user first. And at least one (micro-)benchmark where
keeping entries uncompressed in memory actually shows significant
positive impact.
I can see it might have the opposite effect depending on how often that
Thanks Lance! Pushed after changing 3078/79 back to 3078.

Would it be worth adding a ZIP File System property similar to createNew which
enables/disables the change that Claes has made having the default be the

Hi,
I also think the regression should be repaired and maybe we can have an option
like "lazy compress" to avoid compression on write but defer it to zipfs
closing time.
It should also be possible to parallelize deflation during close, shouldn't it?

Hi,
please review a fix for an issue with zipfs/jarfs regarding multi-release jars.
The issue is observed when an mr-jar does have entries for certain files in the
versioned subfolders but not in the main tree. This should be allowed as per
JEP 238 [0]. So, say, if a jar file contains an entry

Intrusive behavior changes like this should at the very least have been

I’m using the tool I wrote to compress directories with thousands of log files.
The standard zip utility (as well as my utility when run with JDK 12) takes up
to an hour of user time to create the archive, on our server class 40+ core
servers this is reduced to 1–2 minutes.
So while I understa
One of the motivations back then is to speed up the performance of accessing
those entries, means you don't have to deflate/inflate those new/updated

I've marked the bug as potentially affecting the upcoming 11.0.3
release, since the issue that caused this regression is purportedly
being backported to that version.

Both before and after this regression, it seems the default behavior is
not to use a temporary file (until ZFS.sync(), which writes to a temp
file and then moves it in place, but that's different from what happens
with the useTempFile option enabled). Instead entries (and the backing

Sorry should have picked up on this earlier. Can you please update the

Very good, thank you!
Also note that the "new" implementation also requires *a lot* more heap, since
all *uncompressed* file content is copied to the heap before deflating.
