In a full and incremental build we get warnings like these:
/bin/find: ���/home/cphillim/hg.local/9clean/hotspot/test/compiler/native���: No such file or directory
/bin/find: ���/home/cphillim/hg.local/9clean/hotspot/test/compiler/native���: No such file or directory
/bin/find: ���/home/cphillim/hg.local/9clean/hotspot/test/compiler/native���: No such file or directory
/bin/find: ���/home/cphillim/hg.local/9clean/hotspot/test/compiler/native���: No such file or directory
This occurred earlier, with JDK-8162999, which has since been fixed.
However, the fix for JDK-8067744 seems to have reintroduced the problem.
The fix is to remove this line:
$(HOTSPOT_TOPDIR)/test/compiler/native \
from BUILD_HOTSPOT_JTREG_NATIVE_SRC in hotspot/make/test/JtregNative.gmk.
