RE: RFR(M): 8201593: Print array length in ArrayIndexOutOfBoundsException.

Hi Simon, I chose hyphens because they are used in other AIOOB messages, too. But others (including me) seem not to like them either, so I'll leave them out. Best regards, Goetz. > -Original Message- > From: Simon Nash [mailto:si...@cjnash.com] > Sent: Freitag, 20. April 2018 17:17

[PATCH] Prefer TMPDIR over hard coded /tmp

For MacOS and Windows, Java prefers the user's temporary directory for java.io.tmpdir, but not for Linux, where it is always set to /tmp. The burden with this is that if you want to use a different temp directory, you have to explicitly pass -Djava.io.tmpdir=... on the command line, which can b

[PATCH] Add compareToUnsigned to java.nio.*Buffer

The proposed patch is an improvement for Byte/Short/Int/LongBuffer classes to add compareToUnsigned() that works like compareTo() but treats the values as unsigned to leverage the vectorized mismatch implementations, which are not publicly accessible. In addition to that, it adds mismatch() fo

Hi Hamlin, Do you have a sense of what rmi tests are problematic to run concurrently? Maybe you can subset to reduce the increased impact on execution time? Paul. > On Apr 20, 2018, at 12:21 AM, Hamlin Li wrote: > > Is someone available to review the following patch? > > Thank you > > -Haml

Re: [PATCH] Add compareToUnsigned to java.nio.*Buffer

Hi Robert, Thanks. The addition of mismatch is reasonable. I am unsure about compareToUnsigned, since we are trying to be a conservative about what we add to Buffer. I’ll take a closer look but it may take a little while to get around to it. Would you mind logging a web bug and attaching your

Re: [PATCH] minor regex cleanup: use switch for enum

FWIW I strongly doubt this will improve performance; probably the opposite in fact, as IIRC an enum switch generates an extra class (though perhaps this has changed). The original code was quite compact and utilized identity comparisons, and given there are only three alternatives it probably was
