With 3.0RC3 on Debian testing, I'm trying to debug a program. The first time I can debug ok. Some time after that, (not exactly sure when and not completely reproducible), trying to debug gives no response. On the console I fired up eclipse from, I see: jlquinn@tiamat:~$ java.lang.NullPointerException at org.eclipse.core.internal.jobs.Worker.run(Worker.java(Compiled Code))java.lang.NullPointerException at org.eclipse.core.internal.jobs.Worker.run(Worker.java(Compiled Code))java.lang.NullPointerException at org.eclipse.core.internal.jobs.Worker.run(Worker.java(Compiled Code))java.lang.NullPointerException at org.eclipse.core.internal.jobs.Worker.run(Worker.java(Compiled Code))
CC John (A). The NPE looks like job code, but there is not much info from the trace. Is there something else in your log, Jerry?
Closing. Please re-open with steps to reproduce or with .log file attached if this continues to be a problem.

Reopened. I know I can reproduce it by just doing some debugging, but I don't know if it's related to my workspace or what.
Just saying "it happens" isn't much of a help to us :-) What's in your .log file?
(Oops didn't see comment#3 - bugzilla mail is out of order).
After this happens, I don't seem to be able to debug or run anymore.
I noticed you using a 1.4.1 VM - can you try a 1.4.2 VM? It may be a JIT bug.
I've been using IBM's 1.4.1-0.0 java rpm. I just pulled down 1.4.1-2.0, so will try again.
The same problem still shows up quite quickly with the IBM java 1.4.1-2.0 jdk. So far, it doesn't show up quickly with Sun 1.4.2_01. I'll keep looking out for it.
Note that there is also an IBM 1.4.2 VM.
How do I find it? I checked the IBM java site and only found 1.4.1 (for linux)
This could be a duplicate of bug 68452

Andrew, please state what VM you are using, and attach the log file if it contains anything from the time of the crash.
The .log file doesn't contain anything. The jvm I was using is IBM's 1.4.1 Classic VM (build 1.4.1, J2RE 1.4.1 IBM build cxia321411-20030930 (JIT enabled) If I switch to Classic VM (build 1.4.2, J2RE 1.4.2 IBM build cxia32dev-20040524 (JIT enabled) or with -vmargs -Xj9: J2RE 1.4.2 IBM J9 build 20040519 (JIT enabled) then it doesn't seem to happen anymore.
Jerry, when you said that this bug "doesn't show up quickly" on JDK 1.4.2, do you mean that you weren't able to reproduce it after brief testing or that you did reproduce it but only after a few tries? What I really want to know is if this has been reproduced on a VM other than IBM 1.4.1. Either way, can you reproduce the problem on Eclipse 3.0?
So far I haven't seen it at all under Sun 1.4.2. I also have not seen it under 3.0 final with the IBM jvm, so hopefully it got squashed.
Ok. So it was either a dup of bug 68452 or a bug in IBM 1.4.1.

This just happened for me with released eclipse 3.0. The second attached log file is from 3.0 release. Still IBM JVM 1.4.1_3.0.0
Comment #19 sounds correct to me. This looks like a bug in the IBM 1.4.1_X VMs. Has anyone seen this on a 1.4.2 VM?
Moving to JCORE. Could be a JRE bug, but the NPEs are coming from JCORE, not JDT-DEBUG.
NPE is in code used by indexer. Kent please have a look and close as VM bug if everything is fine on our side.
