Improved JAVA support for Linux distributions

About the font problem with open JDK.

Forum: http://www.docear.org/support/forums/docear-support-forums-group3/bug-reports-forum6/docear-v-1-1-stable-release-wont-start-on-linux-thread940/ I've found the solution for openjdk fonts problem. It's antialias problem of freemind or openjdk. https://wiki.archlinux.org/index.php/Java_Runtime_Environment_Fonts I've add "export _JAVA_OPTIONS='-Dawt.useSystemAAFontSettings=on'" in the beginning of docear.sh. Result is good font render. It's very rough method to add variable to java environment, but it works. I'm fink that devs should add this variable to docear script if only it starts from openjdk.

I just used an online tutorial and updated and installed the font fixes of open-jdk and the problem is solved up to a degree. sudo add-apt-repository ppa:no1wantdthisname/openjdk-fontfix sudo apt-get update and this is the way to revert it: sudo apt-get install ppa-purge sudo ppa-purge ppa:no1wantdthisname/openjdk-fontfix

I think the best way to avoid the font rendering issue is to just disalbe AA if Docear detects that it is used with openjdk on a Linux system

[stlanger]

create an option to disable AA --> no check for JVM and OS needed and the user has full control

oracle java 8 completely fixed all rendering and menu issues for me.. closing for now

OpenJDK 8 also fixes all rendering issues for me on Ubuntu 15.04.
