MinimWatch 2.0.12 for Mac gives JavaHomeError

[simoncn]

The fix for this problem with Apple Java 1.6 is now available in MinimServer and MinimWatch 2.0.13. It look longer than expected because I found some other issues while testing.

For some time, the Open button on the dialog about MinimServer and MinimWatch being downloaded from the internet when you start them for the first time has not worked. The workaround is to launch MinimServer or MinimWatch again but this is not how things should be. A fix for this problem is in 2.0.13.

Also, recent JDKs such as JDK 11 and JDK 14 were not being detected by the MinimServer and MinimWatch launch scripts, which could cause the user to be prompted to install Java 8. This is fixed in 2.0.13.

Finally, recent JDKs such as JDK 11 and JDK 14 are unable to run on some older versions of macOS. They work with 10.13 (High Sierra) or later but not with 10.12 (Sierra) or earlier. This is because the macOS code signing mechanism changed in 10.13. It is possible to build applications (such as MinimServer and MinimWatch) that work with both the new and old code signing mechanisms but Java has not been built like this and it is not possible for MinimServer and MinimWatch to work around it. Instead, 2.0.13 shows an alert "JVMLoadError" to warn the user when an incompatible version of Java is installed. A simple solution is to install Java 8, which is compatible with all versions of macOS.
