[jira] [Comment Edited] (LANG-965) FieldUtils methods leak
accessible flags
[ https://issues.apache.org/jira/browse/LANG-965?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14124445#comment-14124445 ]

----------------------------------------------------
Possible simplification:
{code}
+ final boolean originalAccessibility = field.isAccessible();
if (forceAccess && !field.isAccessible()) {
{code}
could be written as
{code}
+ final boolean originalAccessibility = field.isAccessible();
if (forceAccess && !originalAccessibility) {
{code}
Alternatively, just set a flag when accessibility is forced:
{code}
boolean wasInaccessible = false;
if (forceAccess && !field.isAccessible()) {
wasInaccessible = true;
...
}
...
finally {
if (wasInaccessible) {
field.setAccessible(false);
}
}
{code}
This avoids a redundant setAccessible() call where the accessibility was not changed

> When various FieldUtils methods are called the accessible is set to true but never reset to false. This is side-effect should be cleaned up.
> This makes a mess of the object model which represents the class meta data.
