loadShape() problems with SVGs that have . starting a number in a path
Re-saving the SVG in 1.0 format with Illustrator instead of 1.1 will fix the issue, but the problem seems to be that a leading . in the SVG path code won't render properly, for instance:
M3,.6– parse toM,3,.6(may be fixed with https://github.com/processing/processing4/commit/9ef40ba48c284ae52e7eae759af325486ca85f1e)M.6.7– parse toM,.6, and.7- …etc
This caused a problem with the variable icons, which was fixed commit 805306fd1b4eeeac35bf1c29693d751edf349f57, so using the previous version of the SVGs should do the trick for testing.
Test code:
static final String[] names = {
"array", "boolean", "byte", "char", "double", "float",
"integer", "long", "object", "short", "string"
};
void setup() {
size(250, 550);
textAlign(LEFT, CENTER);
textSize(24);
fill(0);
int each = 50;
int pos = 0;
for (String name : names) {
PShape s = loadShape(name + ".svg");
shape(s, 0, pos, each, each);
text(name, 60, pos + each/2);
pos += each;
}
saveFrame("issue.png");
}

This may be the same as https://github.com/processing/processing4/issues/515
I worked with SVG files had also caused ArrayIndexOutOfBoundsException due to the parsing of the path data and in my case the exception was gone with Processing 4.2 , so It seems the fix for #515 also fixes #518 ? thanks @benfry for the fix
