Previously, DefaultResourceLoader instances were created using the
default constructor. This causes the resource loader to capture the
TCCL that was in place at that time. This can lead to a class loader
leak if the resource loader is referenced directly or indirectly from
a static field of a class loaded by a different class loader.
This commit updates the creation of DefaultResourceLoader instances
in main code so that the resource load will use the class loader of
the creating class. In almost all cases this will be the same class
loader as was the thread context class loader that was being captured
so the change in behavior is minimal. Crucially, it will still address
the situation where the TCCL was different.
Note the DevTools' ApplicationContextResourceLoader has been updated
to explicitly use the TCCL. This ensures that it uses the restart
class loader which is required for DevTools to function correctly.
Fixes gh-20900
Prior to this commit, default error responses included the message
from a handled exception. When the exception was a BindException, the
error responses could also include an errors attribute containing the
details of the binding failure. These details could leak information
about the application.
This commit removes the exception message and binding errors detail
from error responses by default, and introduces a
`server.error.include-details` property that can be used to cause
these details to be included in the response.
Fixes gh-20505
Previously, DevToolsDataSourceCondition called
getBeanNamesForType(Class) which could trigger unwanted initialization
of lazy init singletons and objects created by FactoryBeans.
This commit updates DevToolsDataSourceCondition to prohibit eager
init when getting the names of the beans of a particular type.
Fixes gh-20430
This commit changes uses of ClassLoader.loadClass to Class.forName for
consistency with what was initiated in #19342 and better compatibility
with GraalVM.
Closes gh-19824
This commit makes sure that any subsequent call on addProtocolResolver
on the context will impact the ResourceLoader implementation that
DevTools sets on the context.
This makes sure that any custom ProtocolResolver that is set later in
the lifecycle is taken into account.
