You have significantly reduced the pain in this process. Let me just emphasize for others that you MUST download the source of the Mylyn dependencies, linking to the compiled binaries that ship with eclipse doesn't work.

2012-07-11T23:43:45.387+02:00

I can reproduce this 100% of the times on a Windows 7 machine. It is definitely a bug in the JVM, as it is only reproducible with 1.7 (not 1.6 or 1.5)

Sir, you have just saved hours of my time and I'll be eternally thankful!! Pity it's not one of the top google search results when querying for JAR hell, which I just got into. The exclusion tip worked !! :)

You are a LIFE SAVER. Thank youuuuuu

hi,

it's neither Java 7 nor Maven 3 problem - it's Windows and it can be easily worked around: http://blog.bielu.com/2011/11/hotspot-64bit-server-hangs-on-socket.html

2011-12-16T11:52:54.016+01:00

I also changed from Maven 2 to 3. I also installed Java 7.
I faced one problem. The combination Windows 7, Java 7 and Maven 3.0.3 didn't work. Downloading artifacts from the Maven repository got stuck.
After a long search on Internet i discoverd that Java 7 and Maven 3 can result in this problem. I nnstalled Java 6 and it worked.

We had similar problem on windows vista machine and the reason was
TCP Window Scaling Auto Tuning.

You can try to disable it, as described here: http://www.mydigitallife.info/disable-tcp-auto-tuning-to-solve-slow-network-cannot-load-web-page-or-download-email-problems-in-vista/

Hope this helps.

@Jörg - yes, this is a workaround I posted as a comment to the bug report.

Thanks for your comment

Hi Przemysław

and did that help anything?

2011-11-27T09:48:11.968+01:00

Doubt its your problem but the while loop should be using -1 instead of 0.

Thanks!

Yeah, it's here! Erm, with a couple of nasty compiler bugs making it completely useless (http://www.lucidimagination.com/blog/2011/07/28/dont-use-java-7-for-anything/). Great job, Oracle!:/

In fact both have advantages and disadvantages and current versions of Eclipse support both templates - it's up to you which OO principle you want to sacrifice (yes, Bloch suggests fine solution to avoid sacrifice but it's not always acceptable too).

About Hibernate - yes you should be careful but "you should better not override equals if you use Hibernate" is a huge exaggeration. You may and should (if you need) override equals while using Hibernate - just do not take into account DB id.

2011-07-29T12:48:11.449+02:00

Your Solution may be buggy as well.

Have a look at Bloch's Effecive Java Chapter on Equals to see why - instanceof may not be sufficient in equals, because any equals that allows an instance of a class and its superclass to be equal may violate transitivity.

In addition to that, you should better not override equals if you use Hibernate. Any equals on fields that may change within a session, namely the id, is strictly prohibited in hibernate (see hibernate documetation on this).

Thanks for nice words - I'd love to continue it but I haven't had any time recently (as you can see from my (in)activity on the blog.

Will try later :)

OK, this is a rather old post but my thoughts.

UML is a problem looking for a solution. The problem is most people do not recognize that languages like:C/C++/Java/Objective C and such are actually design languages and not executable code. There is no need for an additional layer of abstraction to define the entire project.

There is a belief in academia that a pictorial representation is easier to understand than actual text but that was disproved 1,000's of years ago by the Babylonians. Software is, fundamentally, defining a process; processes are best described with words and not pictures. That is why we still do not understand cave paintings because we have missing context. Are they hopes or are they examples of what happened? Are they stories of events or allegories? We do much better with languages like ancient Egyptian.

So basically, UML is setting us back 1,000's of years in the software definition process because to get concrete enough to define a process, the notation becomes substantially more complex than simple languages like C++.
