According to @walro in #6615 (comment) the affected path with spaces is where Oracle JDK 8 installed on MacOS (/Library/Internet Something). This differs from where my system installs, in /LIbrary/Java/JavaVirtualMachines and may indicate a new layout for JDKs in newer MacOS releases.

I have asked for more information.

Thanks!

I noticed this since I, for reasons I do not remember now, had my $JAVA_HOME pointing at /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home. It's the "JRE path" of Oracle's Java installation, see for example:

• https://docs.oracle.com/javase/8/docs/technotes/guides/install/mac_jre.html#A1097025
• https://docs.oracle.com/javase/9/install/installation-jdk-and-jre-macos.htm#JSJIG-GUID-5F4A0659-BFC5-4CB9-9920-D2DEABF29894
• https://docs.oracle.com/javase/10/install/installed-directory-structure-jdk-and-jre.htm#JSJIG-GUID-F7178F2F-DC92-47E9-8062-CA6B2612D350

indicate a new layout for JDKs in newer MacOS releases.

I think it has been like this "forever", I might just be odd favoring a JRE installation (I generally don't do any Java development) ;-)

@walro Aha that explains it! We should run fine with a JRE so that is no problem, but I did not realize that the Oracle JRE gets installed in a path with spaces (and referencing the long-deprecated Applet feature, no less!)

I will look into adding a test for this situation, at least when on MacOS and such a path is available.
