----------------------------------------
Summary: RequestProcessor does not prevent from accidental
Thread.contextClassLoader changes
Key: NETBEANS-334
URL: https://issues.apache.org/jira/browse/NETBEANS-334
Project: NetBeans
Issue Type: Bug
Components: platform - Other
Affects Versions: 8.2
Reporter: Svatopluk Dedic
In run tasks in a dedicated RequestProcessor; sometimes the task gets an
unexpected context ClassLoader in the worker thread. The RequestProcessor code
tries to remember the context CL in effect when it enqueues a Runnable.
But it seems that the remembered CL is only applied if a new Processor (thread)
is immediately available within the RP's limits. If the task is enqueued for
later execution because limited RP's throughput, the CL is not set to the
Processor prior to execution of the task.
The value of Thread.currentThread().getContrextClassLoader() is therefore
undefined in code run within RP.
The source however suggests that the original idea was to transfer both
(global) Lookup and context classloader to the worker code.
