jstack output

After working for more than 30 minutes NetBeans starts using 100% of both my CPU cores and, when I close the IDE, the processes are still running and I have to manually kill them.

With htop I can see multiple processes as following:

  PID USER      PRI  NI  VIRT   RES   SHR S CPU% MEM%   TIME+  Command
 4755 paolo      20   0 1368M  737M 15616 S 110. 18.7  2h03:38 /usr/lib/jvm/java-7-oracle/bin/java -Djdk.home=/usr/lib/jvm/java-7-oracle -classpath /usr/local/netbeans-dev/platform/lib/boot.jar:/usr/local/netbeans-dev/platform/lib/org-openide-modu

I tried changing JDK but it happens with both OpenJDK7 and OracleJDK.

I attach a jstack output of the process and Netbeans logs.

Thanks.

I added the snapshot, any help on how to fix this is very appreciated, it's a few months this problem is bugging me and it forces me to restart and kill the processes at every 30 minutes.
Thanks.

The Editor Parsing Loop thread is parsing php for the whole time of the snapshot, which accounts for the CPU usage - reassigning to PHP
