Mauve - bacterial genome viewer?

HI,

I'm trying to use MAUVE to visualize mitogenomes,

ending up in java error (below), suggestions please.

**MAUVE**

JAVA_ARGS="-Xms200M -Xmx500M"

**Variables in .zshrc**

java.lang.Integer.parseInt(Integer.java:638)

this error occurs when the sofware try to parse an integer...

Mauve.hasRequiredJVM(Unknown Source)

while trying to parse the java version

the source is here: https://svn.code.sf.net/p/mauve/code/mauve/trunk/src/org/gel/mauve/gui/Mauve.java

private boolean hasRequiredJVM () {
    String jvm_version = System.getProperty ("java.version");
    int minor_version = Integer.parseInt (jvm_version.substring (2, 3));
    if (jvm_version.charAt (0) == '1') {
        if (minor_version < 5) {
            MyConsole
                    .err ()
                    .println (
                            "Sorry, Mauve requires at least Java version 1.5 to operate correctly");
            return false;
        }
    }
    return true;
}

so this tool was not designed for a java version >= 10.

You can always try to fool java by adding a "java.version" property (https://stackoverflow.com/a/5189966/58082)

-Djava.version=1.5

to the java command line (not tested)

Or you can try to re compile from source, and set

boolean hasRequiredJVM() { return true;}

That's true works only with Java 8.
