1.7 +// Rationale behind JVM_FindClassFromBootLoader
1.8 +// a> JVM_FindClassFromClassLoader was never exported in the export tables.
1.9 +// b> because of (a) java.dll has a direct dependecy on the unexported
1.10 +// private symbol "_JVM_FindClassFromClassLoader@20".
1.11 +// c> the launcher cannot use the private symbol as it dynamically opens
1.12 +// the entry point, so if something changes, the launcher will fail
1.13 +// unexpectedly at runtime, it is safest for the launcher to dlopen a
1.14 +// stable exported interface.
1.15 +// d> re-exporting JVM_FindClassFromClassLoader as public, will cause its
1.16 +// signature to change from _JVM_FindClassFromClassLoader@20 to
1.17 +// JVM_FindClassFromClassLoader and will not be backward compatible
1.18 +// with older JDKs.
1.19 +// Thus a public/stable exported entry point is the right solution,
1.20 +// public here means public in linker semantics, and is exported only
1.21 +// to the JDK, and is not intended to be a public API.
