Hi,I've discovered a critical bug in LiClipse 1.0, 1.1, 1.2, 1.3 and 1.4 (Ubuntu 14.04 and 14.10), which eats cached system memory by chunks (maybe 64MB chunks), never releases them even when needed and leads to Swapping and OS OOM.Tried with the bundled JRE, Oracle JDK 7, 8, and OpenJDK 7 32 and 64bits, and OpenJDK 8. Same bug.After months, I've found that this bug occurs when Preferences -> General -> Appearance -> Use mixed fonts and colors for labels is checked.I have a 12GB system and every 2 or 3 tabs opened, 120MB extra RAM is taken forever (in cached system memory. The Java heap size keeps stable) and locked until I quit LiClipse. Other actions or dialogs also take RAM forever. (I've already freed 9GB of RAM several times just by leaving LiClipse). I can lock 1GB and make it unusable just by opening and closing 15-20 tabs.When this option is unchecked, cached memory usage seems to return to normal.
