Developer Notes

Potential Gotchas

  • When moving from Mac OS X's IntelliJ to the IntelliJ of Linux Mint, the tools.jar of OpenJDK/Oracle JDK was not picked up. I needed to manually open up the SDK being used and add the tools.jar of /usr/lib/jvm/java-7-openjdk-amd64/lib/ to the classpath. This allows me to use the Sun-based com.sun.jdi package for a Java debugger interface rather than C++.

  • When using the launching debugger, I noticed that it was creating an address of corresponded to my host name. Attempting to telnet into the address and port provided resulted in a failed connection. Switching my hostname to locahost allowed the main process (and telnet) to connect and use the JVM process.
