Subject: [PATCH] Close Plugin Class Loaders on Disable
|
|
|
|
This should close more memory leaks from /reload and disabling plugins,
|
|
by closing the class loader and the jar file.
|
|
|
|
Note: This patch is no longer necessary as upstream now also closes
|
|
PluginClassLoaders on disable. This patch is now only to keep around
|
|
API methods it previously added, and to add back the log message when a
|
|
PluginClassLoader fails to disable, as upstream decided to ignore the
|
|
exception.
