Hi Ali,
Can the issue be resolved by using different call modifiers on the
affected functions?
Some build / link issues were resolved by adding / removing JNICALL
modifier, see
https://bugs.openjdk.java.net/browse/JDK-8201226
http://mail.openjdk.java.net/pipermail/build-dev/2018-April/021553.html

Regards,
Alexey

Hi,
An issue (https://github.com/AdoptOpenJDK/openjdk-build/issues/709) raised
against AdoptOpenJDK jdk11 32-bit windows builds led us to the name decoration
problem on built 32-bit dlls - specifically dt_socket.dll and dt_shmem.dll.
Whereas 64-bit MSVC builds don’t apply any name decorations on exported
functions, 32-bit builds apply them - which requires either def files or
/export flags to be specified on the linker arguments.
Although the expected linker arguments were present on previous jdk makefiles,
they were removed in jdk11 makefiles.
Below is the proposed patch, which can also be browsed at
https://github.com/AdoptOpenJDK/openjdk-jdk11u/pull/1.
Would you please have a look and let me know of any points I may have missed (I
don’t have any background information about why the export flags were removed
in jdk11)?
Regards,
Ali
