Re: fast way to infer caller

Some loggers do need to find the location of the log statement (class and line where the logger is used not where it is instantiated). for those (it makes loggers more useful) getting the call site is time critical even if they are not in tight performance critical loops. But it actually does

Re: RFR: 8285445: cannot open file "NUL:"

Is that really a needed fix? enabling ADS and less strict parsing might introduce vulnerability but on the other hand NUL: should be allowed for it is a drive style not a ADS. I would also think the number of users who want use NUL: is smaller than the number of users who benefit from ADS

Zlib update

Since the new upstream version for zlib 1.2.12 is available since 4 weeks and I don’t see them in GitHub (not even after April cpu merges) I wonder when is an update planned? (I also noticed at least one vendor claims to have a zlib fix, I am not yet sure if this is a vendor specific thing)

Regression after April Java 17 Update (mime types)

Re: RFR: JDK-8288207: Enhance MalformedURLException in Uri.parseCompat [v3]

The change does not seem to be related to your description, and the description does not match the shown exception. In fact the example stacktrace contains the authority value twice and your change adds a diagnostic which is not really helpful for the case of the underscore? I would not be too

Re: RFR: 8284638: store skip buffers in InputStream Object [v2]

If you consider doing benchmarks in detail maybe consider a static buffer, too? (Especially if it can be used in multiple implementations?) Gruss Bernd -- http://bernd.eckenfels.net Von: core-libs-dev im Auftrag von XenoAmess Gesendet: Wednesday, April 13,

Re: RFR: 8284932: [Vector API] Incorrect implementation of LSHR operator for negative byte/short elements

Hello, Maybe offer operations which can do all variants (shift, roll, signed/unsigned) - maybe even with support for byte/int conversion? Any of those bit fiddling activities in a pipeline can benefit from vectoring. And also, the Javadoc can list the equivalent operator based code and maybe
