I have run into these. This is really very very rare. One time it can happen is if an application does some high end native stuff. An example would be cassandra uses off heap memory to avoid gc. Sometmes the semantics of such features are not clear in the jvm spec i would guess. In any case you might hit a case where the software might get an error loading its data file in one jvm but not the other. I have jad similar issues with commercial vms as well.<br>
<br>I always find out exactly what the developers use and i use that. Oracle jvm is more " enterprise " so it is typically paired with enterprise java products and thus havr better coverage.<br><br>I do a lot of java work and i am rarely aware of if a given system is using one or the other, but i find oracle jvm more compatible. Never found anything that did work right on open jdk and not oracle.<br>
