Dobry den, mam webovou aplikaci, ktera spousti nova vlakna, ve kterych bezi
dlouho trvajici vypocty. Kdyz aplikaci odinstaluju z Tomcatu (verze 7) mam v
logu nasledujici hlasku. Myslim si, ze aplikace korektne neukonci vsechna
bezici vlakna behem odinstalace. Nesetkal jste se nekdo s timto problemem?
Diky za kazdou pripominku.
