[jira] [Created] (GUACAMOLE-1769) KsmRecordService.getField() may throw a NullPointerException if getCustom() returns null
Mike Jumper created GUACAMOLE-1769:
--------------------------------------
Summary: KsmRecordService.getField() may throw a NullPointerException if getCustom() returns null
Key: GUACAMOLE-1769
URL: https://issues.apache.org/jira/browse/GUACAMOLE-1769
Project: Guacamole
Issue Type: Bug
Components: guacamole-vault-ksm
Affects Versions: 1.5.0
Reporter: Mike Jumper
The {{getCustom()}} function of {{KeeperRecordData}} as defined by the KSM SDK is permitted to return {{null}} (it is annotated {{@Nullable}}), however Guacamole's support for KSM assumes that it will always return a {{List}}, resulting in a {{NullPointerException}} if it ever does return {{null}}:
{code:none}
java.lang.NullPointerException
at org.apache.guacamole.vault.ksm.secret.KsmRecordService.getField(KsmRecordService.java:241)
at org.apache.guacamole.vault.ksm.secret.KsmRecordService.getField(KsmRecordService.java:312)
at org.apache.guacamole.vault.ksm.secret.KsmRecordService.getHostname(KsmRecordService.java:397)
...
{code}
Things should be corrected as necessary to handle {{null}} identically to an empty {{List}}.
