Galder Zamarreño commented on ISPN-1554:
----------------------------------------

{code}[INFO] --- exec-maven-plugin:1.1:java (generate_annotation_index) @ infinispan-core ---
ERROR: /qa/home/gzamarreno/code/infinispan.git/core/target/classes/org/infinispan/configuration/cache/TransactionConfigurationChildBuilder.class (Too many open files)
[INFO] {code}

This is tricky, I cannot even build with JDK7 in the cluster machines. Both existing JDK7 releases (7 and 7u1) throw this error in Jandex generation.

> Investigate what's wrong with the JDK7 build:
> {quote}We have noticed the infinispan instance becoming inaccessible/unresponsive due to high CPU (100%) usage. This looks to be exactly the same behavior we saw back in September ...
> I am able to reproduce this problem by running this job:
> https://infinispan.ci.cloudbees.com/job/Infinispan-master-JDK7-tcp
> After about 10 minutes of running this job , I saw CPU spike to 100%. I was tailing the console log in my browser at the time, and saw something strange start to happen to the output:

> It looks as though the first few characters of each line is being chopped off. If you look at the log file on the host in emacs, it looks exactly the same.
