Can you use your IDE profiler or heap management tools to determine what objects are leaking? You should be able to call parse multiple times if you are reading from the same input stream... -- Jody Garnett On Fri, Apr 21, 2023 at 4:47 AM gero.will...@gmx.net <mailto:gero.will...@gmx.net> <gero.will...@gmx.net <mailto:gero.will...@gmx.net> > wrote: Hello togehter, my usecase is using method StreamingParser.parse() in a loop in my java application (ca. 5000 iterations). Unfortunately this leads to a huge memory leak. Also this memory can never be released by the garbage collector. It stays in the old gen heap forever. I use https://github.com/geotools/geotools/blob/main/modules/extension/xsd/xsd-core/src/main/java/org/geotools/xsd/StreamingParser.java <https://ofcsg2dvf1.dwd.de/fmlurlsvc/?fewReq=:B:JVg8NzM3PCBwOzQoNiBvYjs2Nzw2NyB1b2FoZ3JzdGM7PmdjPzIwMWQ1ZDVlNzFjYzdlYzVlMWU0NT4yMDI2MWI+ZT42PmdiPyByOzcwPjQ3NjUwNzcgd29iOzU1Skw2RFdHNjcxMTM1KzU1Skw2RFdENjcxMTM1IHRldnI7VWljdGNoKE1namN1dWNGYnFiKGJjIGU7MzQgbmJqOzY=&url=https%3a%2f%2fgithub.com%2fgeotools%2fgeotools%2fblob%2fmain%2fmodules%2fextension%2fxsd%2fxsd-core%2fsrc%2fmain%2fjava%2forg%2fgeotools%2fxsd%2fStreamingParser.java> in this way: for(.....) { try { org.geotools.xsd.StreamingParser parser = new org.geotools.xsd.StreamingParser(gml, inputStream, Polygon.class); polygon = (Polygon) parser.parse(); } finally { inputStream.close(); } } Do you have any idea why that happens? Are you even able to fix it?
