This patch enables SignTwice test to complete faster on Windows machines. The test starts `keytool` and `jarsigner` a number of times, passing `-J-Djava.security.egd=file:/dev/./urandom` to the started process, presumably to avoid blocking on VMs with insufficient entropy. This works fine on machines where `/dev/./urandom` is actually present. On Windows it makes the JVM use `ThreadedSeedGenerator`, which is very slow compared to the other options.
The fix removes `java.security.egd` setting on Windows machines. Alternatively we could change the egd to use `file:/dev/urandom` (without the `/./` part); this also fixes the Windows problem. Is the `/./` part still needed? If I understand correctly, it was a workaround for some JDK7 bug. ------------- Commit messages: - Remove dev/./urandom on Windows Changes: https://git.openjdk.org/jdk/pull/10160/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=10160&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8293326 Stats: 13 lines in 1 file changed: 10 ins; 3 del; 0 mod Patch: https://git.openjdk.org/jdk/pull/10160.diff Fetch: git fetch https://git.openjdk.org/jdk pull/10160/head:pull/10160 PR: https://git.openjdk.org/jdk/pull/10160
