Absence of deep testing is another issue. OK, I took another look. I guess I had mistakenly looked at the jdk13 patches instead of the jdk14 patches. I did notice one thing: + * BSDNOTE: It's support for fd locking on per thread basis. Since + * FreeBSD libc_r does implement it internally - do nothing here. libc_r does not do fd locking in either -current or -stable. The macros are present, but are disabled by default. You'll need to roll your own. Plus, libkse and libthr won't be doing this either. -- Dan Eischen
