As discussed in RuneMate Release Candidate 1 Features - In Progress we are quickly approaching our first soft release! But before we get there there's a little housekeeping to take care of. One of which is making sure our lovely client is cross-platform compatible. I have begun testing on my Linux VMs and encourage you all to do the same. Dump any and all bugs and stack traces you find here. Linux distributions RuneMate intends on supporting: Ubuntu 12.04 LTS 32/64 bit (Desktop & Server) Fixed client crash due to UnsupportedOperationException for Swing setOpacity Fixed harmless exception at client shutdown due to threads not being shutdown in the right order. Patched bug resulting in UnsupportedOperationException due to Desktop#getDesktop. Ugly PopupDialog with the url for now. Soon to be embedded WebView. Paint is completely broken. Window dragging is slightly jumpy. Audit in progress... Ubuntu 13.10 32/64 bit (Desktop & Server) Audit was a complete failure. There are too many fundamental (non-RuneMate related) incompatibilities and bugs with JavaFX and Ubuntu 13.10. For the sake of efficiently working, support for Ubuntu 13.10 has been abandoned for now. This distribution will be re-explored if there is a user demand for it and/or JavaFX support gets better. CentOS 6.5 32/64 bit Mac OS X Mountain Lion Fixed an IO bug when trying to save biometric data at shutdown. Detected gamebreaking bug caused by JFXPanel incompatibility in Mac OS X. Upgrading to Java 8 as potential fix (unconfirmed). Audit in progress... Note: All fixes listed above are unreleased. Expect them in Beta6/RC1.
