The OpenJDK build system does not support building when the source code resides on a path that contains a space. This requirement is documented in the build instructions but not enforced by the configure script.
This change adds an explicit checks to the wrapper `configure` script that fail the build if the source code to be built is located in a directory who's path contains a space character or the build path cannot be determined. Includes some idiom modernization and shell scripting best practices changes. ------------- Commit messages: - 8294549: configure script should detect unsupported path Changes: https://git.openjdk.org/jdk/pull/10477/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=10477&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8294549 Stats: 24 lines in 1 file changed: 21 ins; 0 del; 3 mod Patch: https://git.openjdk.org/jdk/pull/10477.diff Fetch: git fetch https://git.openjdk.org/jdk pull/10477/head:pull/10477 PR: https://git.openjdk.org/jdk/pull/10477
