-------------------------------------

             Summary: Groovy language in route and no camel-groovy leads to memory leaks
                 Key: CAMEL-10146
                 URL: https://issues.apache.org/jira/browse/CAMEL-10146
             Project: Camel
          Issue Type: Bug
          Components: camel-core
    Affects Versions: 2.15.5
            Reporter: Stefano Rocca


Consider this simple route:

<route id="leak">
	<from uri="file:///c:/temp/leak/in?move=.done&amp;moveFailed=.error"/>
	<setHeader headerName="dummy"><groovy>"dummy" + System.currentTimeMillis()</groovy></setHeader>
	<to uri="file:///c:/temp/leak/out"/>
</route>

each time I put a file in c:/temp/leak/in, the number of instances of org.codehaus.groovy.control.CompilerConfiguration increases by one.
Since each CompilerConfiguration, because of this other issue GROOVY-7884, is created anew and contains a BufferedWriter which in turn contains two buffers of 8192 elements (one char[8192] and one byte[8192]), the heap is soon consumed by useless buffers...
Including camel-groovy in the dependencies the problem disappears.
