JDK jewels from the treasure /bin

JDK has heaps of extremely useful tools in the bin folder, which often make it possible to diagnose a problem without purchasing similar commercial products. Yes, for free and readily available!

What are they good for? To produce and analyse a heapdump, gather exceptions stack traces, see how GC works and what it spends so much time on, check memory content and much more, all from the command line. Does that mean that it will work on a server somewhere far far away, beyond 7 VPNs and without a graphics interface?

During the session, Andrzej presented many of the available tools and talked about what they can be used for and what they can do.

Andrzej Grzesik

I write code because I like it! Most often not far from JVM, somewhere deep inside, near systems with large numbers of users or BigData as that most often means there are non-trivial (interesting!) problems to solve. At the same time, I profess the principle that most software problems start long before any keyboard is even touched. Apart from that I speak at, organise conferences and meets, cycle and read!
