This is indeed a bug that should throw ISE when
ClassLoader.getSystemClassLoader is called during the initialization
of the system class loader, as the spec states.
line 1921: I suggest to revise the message to make it clearer:
"getSystemClassLoader cannot be called during the system class
loader instantiation"
In ClassLoader::initSystemClassLoader (line 1971), when the exception
is thrown via Constructor::newInstance, it would be good to the cause
of an InvocationTargetException like:
+ Throwable t = e;
+ if (e instanceof InvocationTargetException) {
+ t = e.getCause();
+ }
+ throw new Error(t.getMessage(), t);
Better still might be for initSystemClassLoader to re-throw the cause
so that it appears immediately after the "Error occurred during
initialization of VM" message that the VM will fail with.
Yes that would be better.
