I've never done it, but it is definitively possible. You won't be able to run the fullJava VM, only specialized versions of it (JamVM, PhoneME, SableVM). Also please be aware that running a Java VM is fairly a lot overhead for this kind of machine.
我从来没有这样做过，但这绝对是可能的。您将无法运行完整的Java VM，只能运行它的专用版本（JamVM、PhoneME、 SableVM）。另请注意，对于此类机器，运行 Java VM 的开销相当大。
I won't get much in detail because others have already done it. Check out these links.
我不会详细介绍，因为其他人已经这样做了。查看这些链接。

EDIT: SableVM is unmaintained.
编辑：SableVM 未维护。
EDIT: As Amigable Clark Kantmentioned, you could compile your Java code to nativeby using the GNU Compiler for Java.
编辑：正如Amigable Clark Kant 所提到的，您可以使用GNU Compiler for Java将您的 Java 代码编译为本机。

Since your goal is to get the existing solution running on the router, and not explicitly get a JVM running on the router, I would suggest going the other way:
由于您的目标是让现有解决方案在路由器上运行，而不是明确地在路由器上运行 JVM，因此我建议采用另一种方式：
compile the Java code to native! This also has the potential to be just as fast a C code.
将Java代码编译为本机！这也有可能与 C 代码一样快。
There is an article in Linux journalabout this.
If not your cup of tea, JAMVMseems a better fit for a small system such as OpenWRT.
如果不是你的一杯茶，JAMVM似乎更适合像 OpenWRT 这样的小型系统。

I have done this on a Asus WL-HDD some time ago with SableVM. The WL-HDD can run Debianand connect some memory/hdd through USB. But performance was really bad.
前段时间我在 Asus WL-HDD 上使用SableVM完成了此操作。WL-HDD可以运行 Debian并通过 USB 连接一些内存/硬盘。但是性能真的很差。

Use the Embeded JRE these days. http://www.oracle.com/technetwork/java/embedded/overview/index.html
这些天使用嵌入式 JRE。http://www.oracle.com/technetwork/java/embedded/overview/index.html
It also exists for ARM and not only for Intel architecture platforms.
它也适用于 ARM，不仅适用于 Intel 架构平台。
