RFR: 8267403: tools/jpackage/share/FileAssociationsTest.java#id0 failed with "Error: Bundler "Mac PKG Package" (pkg) failed to produce a package"

[Alexander Matveev]

Looks like another issue similar to hdiutil (JDK-8249395) when process is gone, but we still waiting for it. I was not able to reproduce this issue by running test or pkgbuild separately and conclusion was made based on logs. Fixed in same way as hdiutil issue. Also, I added logging PID for external commands to simplify log analysis. Log will have multiple hdiutil and/or pkgbuild processes, since we running multiple tests in parallel and matching external process to test failure requires looking at command line for particular process, so PID should simplify this.
