BUG: build project is very slow after system time adjusted [message #249594]

I adjusted my system time two hours back. Eclipse Europa will build the
project automatically. But it will stay at 1% and make no progress.

Allen,

Just a theory, but I imagine that you might have a Java file with
timestamp x and now the system time has been set to x - 2hr and so when
the .class is produced, the .class still looks older than the .java file
and the system will still want to rebuild it. I suppose your problem
might go away in 2 hours...

Sorry. After the system time is adjusted to 2 hours back, the build
process can be done. But it will stay at 1% and make no progress when
running the project, not the building process.

Restart Eclipse, and run the project again, it will be ok.

The steps to test are as follows.

1. adjust the system time, for example 2 hours back.
2. clean
3. rebuild
4. run (stay at 1% for ever)
5. exit Eclipse
6. run again (ok!)

I have make a test.

1. adjust the sytem time 5 minutes back
2. run the project (will stay at 1%)
3. adjust the system time 5 minutes forward
4. run the project again, ok!

I really wonder why it is ok after Eclipse restarted. Is there anything
wrong with incremental compilation? Since I use other IED, such as
Visual Studio, there is no problem after the system time adjustment. So
I take it a bug of Eclipse.

Allen,

Open a bugzilla. I imagine that with so many important issues for the
JDT guys to look at, messing with the system clock and needing to
restart Eclipse is kind of a nit.
