[aarch64-port-dev ] hotspot jtreg runtime/BoolReturn/JNIBooleanTest.java failure

[Andrey Petushkov]

Hi guys,

Just wanted to ask whether you want this fixed in jdk11. Apparently now raw value of jboolean (i.e. u8) returned by JNI method fed into java code, where it’s treated in different way. (value != 0 vs bit0 != 0) Not sure if it is considered to be belonging to BBB domain or just a mere possibility of application developers to shoot themselves into foot. I’d fix it with proper value conversion at http://hg.openjdk.java.net/jdk/jdk11/file/1ddf9a99e4ad/src/hotspot/cpu/aarch64/sharedRuntime_aarch64.cpp#l1925 <http://hg.openjdk.java.net/jdk/jdk11/file/1ddf9a99e4ad/src/hotspot/cpu/aarch64/sharedRuntime_aarch64.cpp#l1925>
If you’d like I can prepare a patch (although I assume unless it’s BBB-type thing it’s probably too late for jdk11)

Regards,
Andrey
