> I encountered the problem when I tried to learn and run a JDI sample to help myself get
familiar with the JDI library.
> The sample is originally written by Daven and published in http://www.ibm.com/developerworks/cn/java/j-lo-jpda4/index.html.
It runs well with Sun's JDI implementation but fails with Eclipse's JDI implementation.
> With Sun's JDI, the result is:
> =====================================================
> VM started
> Class org.apache.harmony.jdb.HelloWorld is already prepared
> Reach line 10 of org.apache.harmony.jdb.HelloWorld
> The local variable str at line 10 is Hello world! of java.lang.String
> =====================================================
> With Eclipse's JDI, the result is:
> =====================================================
> VM started
> =====================================================
> After the first line printed out, the program seems to be blocked forever.
> The jars that I used to run the sample with Eclipse's JDI are:
> =====================================================
> jdi.jar
> jdimodel.jar
> org.eclipse.core.resources_3.6.0.v20100526-0737.jar
> org.eclipse.equinox.common_3.6.0.v20100503.jar
> org.eclipse.core.runtime_3.6.0.v20100505.jar
> org.eclipse.debug.core_3.6.0.v20100519.jar
> org.eclipse.osgi_3.6.0.v20100517.jar
> =====================================================
> I've asked about the problem in the Eclipse JDT mail list and a guy named Darin Wright,
who seems to be an employee of IBM Canada, tell me that these jars are required to use Eclipse
JDI.
