Fixed:JD-GUI not start on MaxOs Big Sur

[joyven]

When I tried to open the jd-gui in MacOS Big Sur, I reported the following error:

ERROR launching 'JD-GUI'

No suitable Java version found on your system!
This program requires Java 1.8+
Make sure you install the required Java version.

In the startup shell script universalJavaApplicationStub.sh, I print the log and find that $Java_ Home is /bin/java. Obviously, it lacks BASE_PATH, track the discovery of branches, and finally enter the following branches:

elif [ ! -z ${JVMVersion} ] && [ -x /usr/libexec/java_home ] && /usr/libexec/java_home -F; then

	if /usr/libexec/java_home -F -v ${JVMVersion} 2> /dev/null; then
		JAVACMD="`/usr/libexec/java_home -F -v ${JVMVersion} 2> /dev/null`/bin/java"
	else
		# display error message with applescript
		osascript -e "tell application \"System Events\" to display dialog \"ERROR launching '${CFBundleName}'\n\nNo suitable Java version found on your system!\nThis program requires Java ${JVMVersion}\nMake sure you install the required Java version.\" with title \"${CFBundleName}\" buttons {\" OK \"} default button 1 with icon path to resource \"${CFBundleIconFile}\" in bundle (path to me)"
		# exit with error
		exit 3
	fi
elif ...

In this branch, I found that the execution result of command /usr/libexec/java_home -F -v ${JVMVersion} 2> /dev/null was empty, and the error was reported when executing on the command console:

java_home: option requires an argument -- v

Finally, I found that when the v option parameter of java_home command is string containing +, the combination option - F - V cannot be used together.

I think it's better to use https://github.com/tofi86/universalJavaApplicationStub/blob/master/src/universalJavaApplicationStub
