Do threads created in Java behave differently on Windows and Linux?

Question

As what I know, Java is using operating system threads (in contrast to i.e. Erlang), that means that the threads created with Java on Windows and Linux may behave different.

Answer 1

JVM hide all OS differences to you...

as was previously answered the threads on windows are big heavyweight that linux ones.

by experience a heavy multi threading application could have some delays with automatic memory garbage collector and those can generate huge memory peaks.
