Dawid Weiss commented on LUCENE-9241:
-------------------------------------
I'm really indifferent about it - I was just pointing out the fact that such
pattern (opening an url, not the stream) was (and is) a problem sometimes.
Which classloader is going to load tests is often beyond our control; windows
is typically the evil here -- it has limited subprocess command argument line
so gradle may (and I think this is coming in the next version) try to avoid the
problem by forking a launcher which loads JARs in a separate classloader
(arguments from file) rather than using system classpath option.

> Currently each test jvm has Xmx of 512M. With a modern macbook pro this is
> 4GB which is pretty crazy.
> On the other hand, if we fix a few edge cases, tests can work with lower
> heaps such as 128M. This can save many gigabytes (also it finds interesting
> memory waste/issues).
