I have a need to upgrade my version of Java in RAD6. In order to use Jmap, a realtime heap dump utility available in Java 5 or greater, I need to run RAD with JRE runtime Java 5. RAD6 uses 1.4 and Java 1.5 is only available RAD7. Our installation only permits RAD6 at the present time and Java version 1.4 is embedded in the RAD6 runtime configuration. Is there a way to upgrade my RAD6 runtime Java version from 1.4 to 1.5 so that I can use the JAVA Jmap heap dump utility in an online session under RAD6.?
