Andreas Lehmkühler commented on PDFBOX-5731:
--------------------------------------------
I didn't get your point. The following test demonstrates how the cache works
{code}
@Test
void checkCache()
{
COSName nameBlubb1 = COSName.getPDFName("blubb");
COSName nameBlubb2 = COSName.getPDFName("blubb");
// due to the underlying cache nameBlubb1 and nameBlubb2 share the same
instance
assertTrue(nameBlubb1 == nameBlubb2);
assertEquals(nameBlubb1, nameBlubb2);
// clear the cache
COSName.clearResources();
// blubb1 and blubb2 still share the same instances and therefore are
still identical
assertTrue(nameBlubb1 == nameBlubb2);
assertEquals(nameBlubb1, nameBlubb2);
// get another COSName value for "blubb"
COSName nameBlubb3 = COSName.getPDFName("blubb");
// nameBlubb3 is another instance of COSName for the value "blubb"
assertFalse(nameBlubb1 == nameBlubb3);
// both instances are still equal as the underlying strings have equal
values
assertEquals(nameBlubb1, nameBlubb3);
}
{code}
IMHO everything is fine
> org.apache.pdfbox.cos.COSName#nameMap There is a memory leak problem.
