Introducing the HotSpot Virtual Machine for Java
typically used to exclude certain code from being compiled by the HotSpot compiler. The
format of the file is:
exclude classname methodname
for example,
exclude java/util/HashTable rehash
HotSpot will write entries to this file if it encounters a method it is unable to compile, so
that future invocations of the compiler won’t reattempt the compilation. You can manually
add entries to the file as well, if for some reason you wish to exclude a particular method
from compilation. If you want to turn off compilation altogether, use the –Xint switch the
the JVM, which runs HotSpot in interpreted mode. This is roughly equivalent to the
–Xnojit switch of the Classic JVM.
