wang3820 opened a new pull request, #3421:
URL: https://github.com/apache/hop/pull/3421
### Issue
The issue is that in test
`org.apache.hop.core.svg.HopSvgGraphics2DTest#testNewDocumentXml`
and
`org.apache.hop.core.svg.HopSvgGraphics2DTest#testNewDocumentSimpleXml`, inside
`graphics2D.toXml`, `org.apache.batik.svggen.SVGGraphics2D.getRoot`, which uses
a `HashMap` iterator to generate the DOM, is called. Since the order of HashMap
is unpredictable, the order of elements in generated xml string is
nondeterministic.
## Fix
This flaky test has been fixed through leveraging the Jackson library, which
incorporates the JsonNode and XmlParser classes. These components are employed
for parsing two XML strings into tree models, which are subsequently compared
node by node when assertion is called.
I understand this fix introduces a new dependency. If prefered, I'm happy to
come up with a fix without `com.fasterxml.jackson.dataformat.xml.XmlMapper`.
