Something is wrong here. It looks like your ecj is running interpreted
both in the "ecj" and "ecj-native" cases.
$ rpm -q libgcj eclipse-ecj
libgcj-4.0.0-0.30
eclipse-ecj-3.1.0_fc-0.M5.10
$ gcj-dbtool -l /usr/lib/eclipse/eclipse.db | wc -l
19865
$ export CLASSPATH=/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/lib/tools.jar
$ time gij -Dgnu.gcj.precompiled.db.path=/usr/lib/eclipse/eclipse.db \
com.sun.tools.javac.Main HelloWorld.java
real 0m8.687s
user 0m8.591s
sys 0m0.091s
And strace indicates that eclipse.db is opened. Is there anything else
I can check?
