CA Application Performance Management (APM / Wily / Introscope)


My workstation isn't opening after Java upgrade from 1.8 version. Is there are way we can open workstation with an upgraded version of Java?

While launching APM application with the latest 3 jre versions (jre 8u351, jre 8u361, jre 8u371  ) we are getting some warnings from java security stating that the code signing certificate used by the application is using a weak security algorithm,  and hence it’s failing to launch.


APM 10.7 SP3 ( will no longer be supported by  end of the year .

  • Fix is to use either 10.8SP3,10.8 HF3, 10.7 HF 87 or 2x,x


Additional Information

From another KB article:

One of our customer is not able to launch Introscope workstation on windows. 

webstart workstation is failing on .

error message: 

Unsigned application requesting unrestricted access to system

unassigned resource : .... /../...workstationProduct/plugins/org.eclipse.equinox.launcher_1.0.101.R34x_v20080819.jar

java version "1.8.0_351"

Java(TM) SE Runtime Environment (build 1.8.0_351-b31)

Java HotSpot(TM) 64-Bit Server VM (build 25.351-b31, mixed mode)

There was an issue with the 10.7 certificate/key used for signing these artifacts and there was also secondary issue with the time stamp signing certificate. The signing certificate/key was changed on nextgen and on 10.8 several months back. The version is about 2 years and 5 months old.
