During debug sessions, when I have breakpoints enabled, I get the following message in the error log:

Problems occurred when invoking code from plug-in: “org.eclipse.core.runtime”.

The Exception Stack Trace is:

java.version = 1.5.0
eclipse.buildId=M200409161125

Any ideas what is causing this? I am using Eclipse version 3.0.1.

It’s an “all Eclipse” stacktrace, so it’s really not a MyEclipes issue. Personally, I’d try running on JDK 1.4.2, since Eclipse 3.0.1 has not been tested thoroughly on JDK 1.5; there are several issues there.
