Description
jspawnhelper reports error codes back to the parent via pipe. That write may fail. We do not check the return code. On Linux, where I test experimental posix_spawn support, gcc complains: /shared/projects/openjdk/jdk-jdk/source/src/java.base/unix/native/jspawnhelper/jspawnhelper.c:52:5: error: ignoring return value of ���write���, declared with attribute warn_unused_result [-Werror=unused-result]
