+qemu-user warnings confuse userland applications
+
+I recently observed that warning messages emitted by qemu-user can confuse applications when reading from stdout/stderr. This was observed with the configure script of OpenJDK-11 on qemu-sh4:
+
+configure: Found potential Boot JDK using configure arguments
+configure: Potential Boot JDK found at /usr/lib/jvm/java-10-openjdk-sh4 is incorrect JDK version (qemu: Unsupported syscall: 318); ignoring
+configure: (Your Boot JDK version must be one of: 10 11)
+configure: error: The path given by --with-boot-jdk does not contain a valid Boot JDK
+configure exiting with result code 1
+
+See: https://buildd.debian.org/status/fetch.php?pkg=openjdk-11&arch=sh4&ver=11%7E18-1&stamp=1529119043&raw=0
+
+Commenting out the line of code which emits the warning fixes the problem for me and the configure script finishes without problems.
+
+Thus, qemu should be modified to avoid cluttering stdout or stderr with its own messages and rather send those warnings to a log file or similar.
