I cannot reproduce: When saving &.osm from JOSM, <entry value='/tmp/&amp;.osm'/> is written to the preference file. U+2642 works, too.

When editing the preference file by hand, make sure to correctly escape characters like &.

Ok, here is a real world example.

Create the test dir and test file (execute the attached bash script).
Then open the created test GPX-file, close JOSM.
You will find the following lines in preferences.xml:

  <list key='file-open.history'>
    <entry value='/tmp/DIR&#xD;TEST/test.gpx'/>

Start JOSM, an error occures:

Preferences file had errors. Making backup of old one to /home/test/.josm/preferences.xml.bak and creating a new default preference file.

Now you can reproduce.

By the way:
HAL creates this funny mountpoints, if a USB mass storage device (GPS device or smartphone) sends a identifier, containing this characters.

According to ​http://www.w3.org/TR/xml/#charsets, U+001A is not a valid XML character. For that reason, Xerces refuses to parse this one – escaping as &#26; or &#x1A; does not help. Not sure how to fix this.

Minimum would be not to create invalid files...

I attached a possible fix. Avoids invalid XML file. In this case, the file entry in "Open Recent" does not exist.

comment:7 by bastiK, 12 years ago

#x1A is valid in XML 1.1: ​http://www.w3.org/TR/2006/REC-xml11-20060816/#charsets, but must be escaped as entity.

Not sure if XML 1.1 is supported by Java, changing the header in preferences.xml makes JOSM stall without any output.

#7648 is related.

Replying to bastiK:

Not sure if XML 1.1 is supported by Java.

It seems to be, at least there's a basic support. However, we also need XSD 1.1, which became a W3C recommendation in April 2012... I don't think we'll see it in Java SE before Java 9 at least.
