Windows XP - C:\Documents File Not Found

[romario89]

On Windows XP Emacs-25.2 meghanada-1.2.0.jar and meghanada-20190526.548 I open a sample Java file to check meghanada. Meghanada starts and displays Please wait. Meghanada indexing ... But it doesn't diplay Meghanada ready
When I edit the file classnames and method names come as dropdown, i.e. meghanada works at least partially. But on the messages I see

WARN not match type
Error:File . Please check *meghanada-server-log*

and

Error:c:/Documents . Please check *meghanada-server-log*

On the meghanada-server-log there chunks of code like:

java.io.FileNotFoundException: File 'C:\Documents' does not exist

and

[INFO ][EmacsServe: 352] receive [dl, C:\programs\java\sample\src\MySample.java, C:\Documents, and, Settings\IBMR61\Local, Settings\Temp\meghanada488kTN.java]...

What should I do?

[romario89]

I guess it's got something to do with the Windows XP's path names with spaces on it like C:\Documents and Settings\IBMR61 and when Meghanada tries to read from it, it results in pathnames like these (taken from the code above)

C:\Documents, and, Settings\IBMR61\Local, Settings\Temp\meghanada488kTN.java

You see commas after the names with space: 'Documents, ' That must be causing trouble.

[romario89]

I think I've found the cause of the problem:

The tmpfile in meghanada--write-tmpfile function and the log file in meghanada--start-server-process function, at meghanada.el were using the C:/Documents and Settings/... path. I've harcoded those variables so that they will use the path like: C:/temp i.e. no spaces in path.

After this change, the aforementioned Error:c:/Documents problem disappeared and meghanada server started to print the member functions , the variables and the class objects as a dropdown box. That's good but one more problem occurs which I think is related to the same Windows XP Documents and Settings path. When I enter code in a java file the mini buffer says:

Error while checking syntax automatically...

because in the server log it says:

[ERROR][CommandHan:  49] Catching
java.lang.NumberFormatException: For input string: "**and**"
	at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65) ~[?:1.8.0_153]
	at java.lang.Integer.parseInt(Integer.java:580) ~[?:1.8.0_153]

I guess the and in the log is the and at the Documents and Settings

[romario89]

When I open a simple project named Permutasyon and type this simple Java code

System.out.println("OK");

Meghanada Server says in the mini buffer: WARN not match type
And I get this from the meghanada-server-log

Thats very likely to be caused by the Windows XP's default-directory i.e. C:\Documents and Settings\<username> spaces cause the Meghanada to interpret the line incorrectly.
