I'm working with "SQL Developer" version:
Oracle IDE 4.0.0.13.80
Plataforma Java(TM) 1.7.0_45
installed on windows 7 64 bits.
when I execute some ddl command in the code editor with syntax error, all layout windows are incorrectly drawn, and I have to close "SQL Developer" application to go on.
Example:
COMMENT ON COLUMN "TABLE"."COLUMN1" IS 'comments on column 1';
COMMENT ON COLUMN "TABLE"."COLUMN2" AS 'comments on column 2';
First comment is correctly aplied but second comment has a syntax error (AS is wrong) but you no receive error output, layout it hangs.
I tested with thick/OCI and using jdbc, and I always go to the same problem.
