Compiling a Java-implemented JVM with GCJ

0 votes
33 views

There is a Java Virtual Machine completely implemented in Java called JPF. In other words, when you run a Java program within this machine, it's a JVM-within-a-JVM execution. Obviously, this uses a lot of resources and I was thinking of ways how that could be reduced.

An idea I have is to compile JPF with GCJ to native code, thereby resulting in only one JVM that is used when running a Java program within JPF.

Do you see any inherent limitations to this idea, i.e. reasons why it wouldn't work? I'm not a JVM expert so it's hard for me to see any obvious obstacles.

Nothing obvious. Be aware that GCJ supports an earlier version of the Java libraries, so nothing is guaranteed. Whether it's any faster or smaller I couldn't say.

a. Once tomcat server is configured in local eclipse,I pressed F3 on it.
b. Click on Open launch configuration link.
c. Go to Arguments tab.
d. Add -ea at the beginning of JVM arguments.

Then Finally I restarted my tomcat. Here is what I am getting....

 Server Tomcat v7.0 Server at localhost failed to start.
 Error: Could not find or load main class -ea

Any suggestions...

For lack of funds initially and now for a stalemate in the project, we do not have a JVM monitoring tool yet. JavaMelody was recently discussed. I like the fact that there is a dashboard and history of metrics. In looking at it, I find JavaMelody lacking in in-depth diagnostics of the JVM. Top-N SQL statements, Transaction Tracing, metrics co-relation, call-back tree, thresholds and alerting are a few.

Are there are any OpenSource projects that instrument the JVM at byte-code and provide detailed metrics more than what JMX offers? Or am I missing something with JavaMelody?
