Test java/lang/ProcessBuilder/Basic.java fails with 'Exception: java.lang.Error: PATH search algorithm" The tests in ProcessBuilder.Basic related to PATH search algorithm use the system binaries for /bin/true and /bin/false. The tests proceed to copy the binaries to different directories on carefully constructed PATHs and verify the correct one is found. On some Linux OS's the binaries for /bin/true and /bin/false are the same binary. Distinguished only by arg[0] when executed. On Ubuntu 25-10, copying the binary to `prog` and launching it, results in the exit status not being the expected value. Musl and Apline systems have other limitations that are already reflected in special cases. A solution proposed here is to provide separate binaries for the true and false functions so their invocation is more controlled.
Use native BasicTrue and BasicFalse executables in cases where /bin/true and /bin/false are not unique. ------------- Commit messages: - 8379122: Test java/lang/ProcessBuilder/Basic.java fails with 'Exception: java.lang.Error: PATH search algorithm" Changes: https://git.openjdk.org/jdk/pull/30150/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=30150&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8379122 Stats: 124 lines in 3 files changed: 99 ins; 0 del; 25 mod Patch: https://git.openjdk.org/jdk/pull/30150.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/30150/head:pull/30150 PR: https://git.openjdk.org/jdk/pull/30150
