Greg Huber updated WW-5101:
---------------------------
Description:
Testing on java 11 AbstractLocalizedTextProvider outputs
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by
com.opensymphony.xwork2.util.AbstractLocalizedTextProvider
(
[file:struts2-core-2.5.26.jar|file:///struts2-core-2.5.26.jar]
) to field java.util.ResourceBundle.cacheList
WARNING: Please consider reporting this to the maintainers of
com.opensymphony.xwork2.util.AbstractLocalizedTextProvider
WARNING: Use --illegal-access=warn to enable warnings of further illegal
reflective access operations
WARNING: All illegal access operations will be denied in a future release
{code:java}
clearMap(ResourceBundle.class, null, "cacheList");
private void clearMap(Class cl, Object obj, String name) throws
NoSuchFieldException, IllegalAccessException,
NoSuchMethodException, InvocationTargetException{
Field field = cl.getDeclaredField(name);
field.setAccessible(true);
Object cache = field.get(obj);
synchronized (cache) {
Class ccl = cache.getClass();
Method clearMethod = ccl.getMethod("clear");
clearMethod.invoke(cache);
}
}
{code}
When it executes the linefield.setAccessible(true); produces the warning.
Seems we might be able to replace
{code:java}
try{
clearMap(ResourceBundle.class, null, "cacheList"); }
catch (NoSuchFieldException e) {
// happens in IBM JVM, that has a different ResourceBundle impl it has a
'cache' member
clearMap(ResourceBundle.class, null, "cache");
}{code}
{code:java}
ResourceBundle.clearCache();
{code}
Tomcat also uses the same method to flush
{color:#000000}resourceEntries{color}. Tomcat checks
org.apache.catalina.loader.WebappClassLoader but for version #9 is using
org.apache.catalina.loader.ParallelWebappClassLoader, so defaults to
{code:java}
clearMap(cl.getSuperclass(), loader, TOMCAT_RESOURCE_ENTRIES_FIELD);
{code}
Commenting out the tomcat reload, the bundles seem to reload ok. Maybe drop
this going forward.
