ADDITIONAL SYSTEM INFORMATION :
Centos 8.4
OpenJDK 11.0.11 2-21-04-20 LTS
JavaFX-16




A DESCRIPTION OF THE PROBLEM :
ClipBoardContent content = new ClipboardContent();
contetn.put(dataFormat.PLAIN_TEXT, Array.asList("A","B")));
Clipboard.getSystemClipboard.setContent(content);

causes the JVM to crash.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and execute this code

ClipBoardContent content = new ClipboardContent();
content.put(dataFormat.PLAIN_TEXT, Array.asList("A","B")));
Clipboard.getSystemClipboard.setContent(content);


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Either array of strings being added to system clipboard or a catchable exception if this data type (list of strings) is not supported.
ACTUAL -
JVM aborts.

CUSTOMER SUBMITTED WORKAROUND :
Pass only a single String to content.put() instead of a List. Presumably, this is the expected data type.. However, bad data should not cause the JVM to crash.

FREQUENCY : always
