displayTrustedInputConfig() shows not available at wlst

 OAM 11.1.1.7 was patched with  BP07 patch.after that we saw below error.

wls:/oam_domain/serverConfig>
wls:/oam_domain/serverConfig> displayTrustedInputConfig()
Traceback (innermost last):
  File "<console>", line 1, in ?
  File "/stage/fmw/112/iam_112/common/wlst/Oam.py", line 681, in displayTrustedInputConfig
AttributeError: 'module' object has no attribute 'displayTrustedInputConfig'

Fix: Its a known issue.

1. Backup all .class files under OAM ORACLE_HOME/common/script_handlers

2.Removed the class files from  OAM ORACLE_HOME/common/script_handlers

For example:

Oam_common$py.class
 OamInternal_handler$py.class

2. Restart both Admin and OAM servers

3.Now it should work.
