such a stream too; a recent request

That's weird, the build for s390x is failing in cross compile:

A previous report too suggests that the JDK build fails (due to compiler
warnings) when using 16.3 of Xcode on macos. Do you have access to a
15.4 version of Xcode instead? If so, then you can use
"--with-xcode-path" during configure to point to that installation of
Xcode and build the JDK (mor

Hi,
The errors seem like they can be fixed by dynamically allocating the
arrays rather than trying to use a non constant expression to set the
array size. As the compiler says, variable length arrays are not
allowed in C++. I unfortunately don't have a Mac to test this fix on
however. Perhaps a ne
