I've had first hand experience with Oracle Coherence at two big investment banks and can say it's definitely stable. However, as with any complex piece of software it's not without it's quirks.
EDIT: Doh, just realised the question is over a year old. Oh well...
Coherence is in production at hundreds of companies. Many of the companies are large financial institutions and large consumer websites. For example, hotwire.com uses Coherence.
As with any technology, Coherence has the capability to meet your needs for performance and robustness. If you understand the technology and implement it correctly, then yes.
I've been using it for a few months now. So far, it's doing fine in production. We haven't gotten to the maintenance part yet.
Oracle Coherence is a mature product, but you need to make sure that you have the latest patches from Oracle. The point releases that are downloadable from the Oracle website have many bugs that are fixed in the patch releases.
As for development and maintenance, the learning curve is a little steeper than the documentation would suggest. I recommend the Oracle training course (or Alek Seovic's book).

我曾在两家大型投资银行亲身体验过 Oracle Coherence，可以说它绝对稳定。 然而，与任何复杂的软件一样，它也并非没有怪癖。
编辑：哦，刚刚意识到这个问题已经一年多了。 那好吧...

与任何技术一样，Coherence 能够满足您对性能和稳健性的需求。 如果您了解该技术并正确实施它，那么是的。
我已经使用它几个月了。 到目前为止，它在生产中表现良好。 我们还没有到达维护部分。

Oracle Coherence 是一款成熟的产品，但您需要确保拥有 Oracle 提供的最新补丁。 可从 Oracle 网站下载的单点版本有许多错误，这些错误已在补丁版本中修复。
至于开发和维护，学习曲线比文档建议的要陡一些。 我推荐 Oracle 培训课程（或 Alek Seovic 的书）。
