It might be permgen space, I'm currently using: MAVEN_OPTS=-Xms1024m -Xmx1024m -XX:MaxPermSize=256m -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC
*-Xms1024m -Xmx1024m* set the min and max the same, so no dynamic reallocation will happen, should be faster :) *-XX:MaxPermSize=256m* sets the size of the permenant generation, you usually need this if you have a large heap *-XX:+UnlockExperimentalVMOptions -XX:+UseG1GC* enables the G1 garbage collector (this need the LATEST java update), which seems to be a bit faster.
