可以将JVM配置为不使用USRSIG1吗?

I have an application (Go) that creates a JVM in a child process. The application has its own use of the SIGUSR1 signal which conflicts with the JVM it seems and crashes.

Here's the only relevant log I've seen from the application:

Warning: SIGUSR1 handler expected:0x0000000000000000 found:<application-name>

I've tried using '-Xusealtsigs' option when spinning up the JVM but that doesn't seem have any effect on USRSIG1 or USRSIG2.

Is there any way to have to JVM not use USRSIG1?

*Note I won't be able to change the signal processing in the main application.
