Unable to remove note in log : Got stderr: Picked up _JAVA_OPTIONS: -Djava.awt.headless=true

[SundareshSankaran]

Summary of your issue

I call the tabula-py package from within a non-standard IDE (SAS Studio), which has the ability to submit Python commands.

I get the following note, which seems benign (I am able to obtain correct output).

Got stderr: Picked up _JAVA_OPTIONS: -Djava.awt.headless=true

However, I would like to remove the same. I changed my command to the following but that didn't work.

table = tabula.read_pdf(file1,pages=1, java_options="-Djava.awt.headless=True" )

If not possible to execute tabula.environment_info(), please answer following questions manually.

• Paste the output of python --version command on your terminal: ?
• Paste the output of java -version command on your terminal: ?
• Does java -h command work well?; Ensure your java command is included in PATH
• Write your OS and it's version: ?

What did you do when you faced the problem?

While tabula-py enforcing setting -Djava.awt.headless=true option for Darwin, it should not set on Linux.

tabula-py/tabula/io.py

Lines 408 to 410 in b24e3bd

	if platform.system() == "Darwin":
	if not any("java.awt.headless" in opt for opt in java_options):
	java_options += ["-Djava.awt.headless=true"]

Looking at your output of tabula.environment_info(), there is same message for "Java version":

Java version:
    Picked up _JAVA_OPTIONS: -Djava.awt.headless=true

However, java_version() calls java command without adding any option. It presumably your environment issue.

tabula-py/tabula/util.py

Lines 28 to 30 in b24e3bd

	res = subprocess.check_output(
	["java", "-version"], stderr=subprocess.STDOUT
	).decode()

If you just want to suppress Got stderr: Picked up _JAVA_OPTIONS: -Djava.awt.headless=true, you can change log level like:

logging.getLogger("tabula").setLevel(logging.ERROR)
