Priority: P2
Bug ID: 53796
Assignee: issues@jmeter.apache.org
Summary: TestCompiler uses static Set which can grow huge
Severity: normal
Classification: Unclassified
OS: All
Reporter: s...@apache.org
Hardware: All
Status: NEW
Version: unspecified
Component: Main
Product: JMeter
The TestCompiler uses a static Set (PAIRING) which can grow very large if there
are lots of threads. This limits the total number of thread groups, even when
using delayed start.
The Set is used to prevent a child being added to the same parent twice.
One possible solution is to save the information in the parent instance, rather
than a static set. At the end of a thread, the parent instance will no longer
be needed, and the memory can be reclaimed. [If there is still a reference to
either parent or child, the memory won't be released, but that applies to the
current implementation also.]
It's not clear whether there can ever be a duplicate ObjectPair, as most test
elements are cloned. But in case duplicates are possible, something like the
above solution is necessary.
