JVM is running out of memory during full Camel build

Hi,

I just tried to build the Camel trunk, but the compiler continues to ran out
of
memory. Note that I have modified Maven options to 1GB of memory:

d:\source\camel>set MAVEN_OPTS=-Xms128m -Xmx1024m
d:\source\camel>mvn clean install -Pfastinstall

Does Maven need more memory? The private working set of Memory never
exceeded 500MB while compiling.
Is there a command to just compile the twitter component?
