Performance Issues

Hello guys,

I’m facing a strange issue. Let me explain:

I’ve been using JDK 1.8.0_51 with no issues. A few days earlier an JDK 1.8.0_60 update comms in place and I tried that. My problem is that all of my JUnit tests become extremely slow. Its a complex ANT-based build system which builds around three EARs. Each EAR consist of several sub-modules which are covered with JUnit.

On JDK 1.8.0_51 the build process takes around one minute. When using JDK 1.8.0_60 it takes more than five minutes.

Well, to be honest, I didn’t debug it yet, need to work on it so I downgraded back to the 51 build. But I’m quite curious what’s going on here. My JUnit version is the default one coming with NetBeans (JUnit 4.10).

I’m using Mac OS X 10.10.5.

Is anybody here experiencing the same problem? Maybe I’ve just mislead some kind of configuration etc…

Thank you very much for your help.

With kind regards,
