Change in loading of .hotspot_compiler and .hotspotrc files

The default implicit loading of the .hotspot_compiler and .hotspotrc files from the current working directory is changed. These files are no longer loaded by default. For existing deployments that rely on .hotspot_compiler (for example, to exclude a method from hotspot compilation), and .hotspotrc, an unsupported behavioral option is provided to simulate the old loading behavior. The following command line options support old behavior:

-XX:Flags=.hotspotrc

reverts to old behavior for .hotspotrc.

-XX:CompileCommandFile=.hotspot_compiler

reverts to old behavior for the .hotspot_compiler.
