Hello everyone, does anybody know how to debug start of java applications? Because I takes like two minutes to start pycharm on my computer which has quite decent params: CPU: intel i5 RAM: 8GB storage: SSD (OS), HDD(data) OS: Linux oglop-pc 4.4.9-300.fc23.x8664 #1 SMP Wed May 4 23:56:27 UTC 2016 x8664 x8664 x8664 GNU/Linux

It took 2 minutes to start, I'm experiencing similar behavior with all Java applications. Thank you.
