2.0: Windows import.bat doesn't run #73

I'm in a position where I need to use the 2.0 branch (I know it's not the master branch so might be unstable).

I really like that you're providing more support to Windows users, though I'm running into an issue. When I first run the import.bat file, regardless of what arguments I give or how many, I get the following exception:

Error occurred during initialization of VM java.nio.charset.IllegalCharsetNameException: UTF-8 -Xmx4G -Xms4G at java.nio.charset.Charset.checkName(Unknown Source) at java.nio.charset.Charset.lookup2(Unknown Source) at java.nio.charset.Charset.lookup(Unknown Source) at java.nio.charset.Charset.defaultCharset(Unknown Source) at sun.nio.cs.StreamEncoder.forOutputStreamWriter(Unknown Source) at java.io.OutputStreamWriter.(Unknown Source) at java.io.PrintStream.(Unknown Source) at java.io.PrintStream.(Unknown Source) at java.lang.System.initializeSystemClass(Unknown Source)

I started having a look through the .bat file and found by not including the EXTRA_JVM_ARGUMENTS in the line where the JAVACMD is called it works fine, kind of. I can't get it to just include the -Xmx4G -Xms4G though and I'm pretty sure when I don't include EXTRA_JVM_ARGUMENTS that the JVM just runs on it's default settings for heap. Which is making my imports ridiculously slow.

Any help/fix appreciated.

@craigbrett17 I just fixed that last night. Did you pull a new update of the zip-file?

Windows didn't like the double quotes around the EXTRA_JVM_ARGUMENTS, removing them helped.

@jexp I hadn't at the time I raised this, I was a couple of days out. I have now though and it works fine off the bat. Thanks!
