Test program to reproduce the error

Running the attached test program gives an error:

$ javac Test.java && java Test
Exception in thread "main" java.lang.UnsatisfiedLinkError: sun.nio.ch.FileDispatcherImpl.allocate0(Ljava/io/FileDescriptor;J)I
        at sun.nio.ch.FileDispatcherImpl.allocate0(Native Method)
        at sun.nio.ch.FileDispatcherImpl.allocate(FileDispatcherImpl.java:84)
        at sun.nio.ch.FileChannelImpl.map(FileChannelImpl.java:909)
        at Test.main(Test.java:11)

There is an implementation for allocate0 in src/solaris/native/sun/nio/ch/FileDispatcherImpl.c. I guess it's only a problem with the build system.

I'm not 100% sure but I think the program that now throws this error used to work about a year ago.
Comment 1 Stefan Ehmann 2019-01-03 19:08:57 UTC 
Seems to be a regression in 8u192. openjdk8-8.181.13_1 works fine.

A short note on the test program:
Make sure that the file "foo" does not exist before running the test.

If you test with 8u181 it creates the file with 1 byte. Afterwards, the error will not occur with 8u192 because the affected code path is only entered if the file needs to be expanded.

A quick fix to fix the runtime error

It looks like the following commit was not correctly merged, i.e., jdk/make/mapfiles/libnio/mapfile-bsd:

http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/rev/f64826e5b775

The easiest fix is using the attached patch.  However, the above commit was reverted later:

https://bugs.openjdk.java.net/browse/JDK-8202261

and fixed differently.

I forgot to mention the attached patch replaces java/openjdk8/files/patch-jdk-make-mapfiles-libnio-mapfile-bsd.

Can confirm that there is no UnsatisfiedLinkError after applying the patch.
Thanks for the quick reply.
